Gadget Guide
Written by Dr. Samuel Centralia, Ph.D., D.D.S., Esq.   
There was a little trouble down in the lab again this week. Loyal readers may recall that Copernicus, my faithful Doberman guard dog, got into some recombinant DNA samples last month and ended up growing a pair of reindeer antlers. I think they look adorable, but he seems a little self-conscious. So I was distilling some retroviral plasmids when I heard a remarkably loud explosion. It seems Copernicus' antlers knocked a beaker of nitrostarch into a percolating ammonium picrate solution. Copernicus, considering his species, has a pretty good understanding of deflagrating explosives, and escaped the lab in time. But we lost a good amount of equipment, and somehow managed to cause a six-hour brownout in Albuquerque. Never a dull moment, I tell you.

But anyway, we're not here to talk about detonations, fun as they may be. We're here to talk about cell phones. Ah, yes – behold the cell phone. Emblem of the Information Age. Ubiquitous, powerful, efficient, occasionally annoying as hell. But above all – so very, very useful. There's a reason everyone has a cell phone; it is the most wildly practical invention since the internal combustion engine. Factoid:  There are now more than a billion cell phones use in the worldwide. .

But enough hyperbole – we here at Dyscern World HQ Labs deal strictly with the cold, hard facts: Here are the most important things to look for when buying a cell phone.
  • What do you really need? This is the most important element. Choices run the gamut from "Just a Phone" to "All-Encompassing Communications Nerve Center." You have lots of options, which is always good for the consumer. Decide early on the features you will actually use, as opposed to the ones that look cool. More on this below.
  • Do you frequently travel overseas? If so, this becomes a critical question -- see GSM vs. CDMA, below.
  • Aesthetics -- what do you like? Here we consider form over function. Cell phones come in four basic flavors: bar phone (no flip), clamshell (flip phone), data phone (keyboard a la rim/palm) and PDA phone (no keyboard, all touch screen). Go with what feels good.
All right, then. Let us commence. Key things to know when looking for a cell phone:

Frequencies - GSM vs. CDMA

GSM & CDMA

  • These appealing acronyms stand for: Code-Division Multiple Access vs. Global System for Mobile Communications. Did You Know: CDMA technology was used to thwart German communications jamming during WW2. Good trivia for cocktail party chatter.
  • For the North American consumer, this essentially boils down to Cingular/T-Mobile (GSM) vs. Sprint/Nextel/Verizon/Alltel (CDMA) For non-U.S. customers, GSM is more or less universal.
  • GSM takes a SIM card; CDMA is tied to the phone. This doesn't really matter all that much, the "user experience," as they say, is essentially the same – unless you travel overseas. GSM is the de facto standard in Asia and Europe. Your CDMA phone will be all but useless. At any rate, if travel overseas is not an issue, it doesn’t matter.

Frequencies

  • With CDMA, it doesn’t really matter. You didn't ask, but I'm telling you anyway: CDMA does not assign specific frequencies -- instead, every channel uses the full available spectrum, and transmissions are encoded with a pseudo-random digital sequence.
  • With GSM, you want to look for 850MHz and 1900MHz frequencies in the U.S.; 900 and 1800MHz overseas.
  • In North America, 850MHz is prevalent in remote or rural areas in particular. Definitely confirm your coverage before buying – that is to say, make sure your phone is going to work where you live.
Having absorbed these technical details, go buy yourself a high-end deli sandwich. As an Informed Consumer, you deserve it.

Locked vs. Unlocked Cell Phones - GSM

This is basically a question of freedom. Unlocked GSM phones let you swap SIM cards -- prepaid, etc. – and there is no contract obligating you to a particular carrier. Locked GSM phones are bound to a particular carrier. It is important to note that with unlocked phones, you will still need to program in your carrier’s Internet settings. It is not that complicated, but it does need to be done. If you don't want to deal with that hassle, then just stick with the locked phone packages for your carrier.
 
If you're shopping from outside the U.S., or plan to use your phone mostly overseas, definitely go with an unlocked phone.

Contract vs. No Contract

The deal here is that the carrier companies actually subsidize the phone manufacturers, thus spawning a subsequent morass of confusing contracts and packages. Carriers and manufacturers are constantly cutting elaborate deals with one another, at an alarming frequency.

Buying a phone without a contract gives you the freedom to choose new plans at will. But it takes more effort to keep on top of things.

When activating, do it over the phone rather than at your local phone retailer. Cell phone carrier shops make money from commissions on new activation. They hate people who buy phones online and will sometimes not activate the handset or manufacture problems. Always call your carrier for activation

Data Phones/Smartphones - Do You Need One?

The first question here – and you'll need to take a hard, unflinching look at yourself – is simple: Are you an e-mail geek? If yes, then get a smartphone. Smartphones are designed handle e-mail as efficiently as current technology allows. If not, a regular will do.

If you're one of those very busy, hyperorganized perople, you'll want superior synchronization features with your smartphone. In this case, Treos and Windows Mobile phones are excellent. Also, RIM Blackberries are pretty good

For pure e-mail awesomeness, nothing beats a Blackberry.  There's a reason they call them Crackberry – they do what they do awfully well, and they do just about everything that can be done on a handheld wireless device. Then, of course, there is the iPhone, which manages to be a cell phone, mobile web/email device, MP3 player, and digital camera all wrapped together by the best industrial design guys in the business.

Data Speed

EDGE, EV-DO, UMTS, HSDPA. What does it all mean? It means more impressive acronyms to throw around at parties!

Basically, this is about network speeds. On a data phone, 3G wirelessly approximates landline DSL speeds. Edge and the others are about one-half DSL speeds.

Unless using your phone as a modem, any speed is fine for e-mail. In general, you want 2G (Edge, EV-DO) or 3G for a modem, otherwise it’s deadly slow. However, if you’re this geeky, you really should just have a smartphone or Blackberry, anyway.

Finally, and we cannot stress this enough, make sure to check on your data plan with your carrier. These can get unnervingly pricey. I forgot to pay my bill once back in the fall of 2006, and somehow managed to collapse the entire Uruguayan economy.

Bells, Whistles, and Advanced Gadgetry

  • Camera. Both still image and short-duration video capture cameras are pretty standard now, and their prevalence has a direct inverse proportion to privacy issues. Thanks to cell phone cameras, everyone is now potentially on camera all the time! Enjoy the sensation of creeping paranoia, everyone! Quality is what you’d expect for something so small. One MP (megapixel) is common now; 2 MP coming on the scene. These resolutions are really only good for digital posting – emails or Web sites – and not for printing. Just to clarify here: 2MP is good for 4x6 pictures, but below that is really just for web or phone resolution…
  • Video Playback. Popular on Verizon in particular, but other carriers as well. You can watch TV, stored video files, even YouTube. It’s incredibly cool, if -- you know – you're cool with the existential ennui that comes with watching TV on your phone.
  • MP3 Player. These are also becoming much more common. Most play pretty well, but features are quite limited compared to a dedicated digital audio player.
  • Expandability. Most recent generation smartphones have removable flash memory cards – typically mini or microSD. You'll need this for MP3 capability. It's not technically required, but you'll want a card if you plan to keep more than a handful of audio files.  (not required, but necessary if you want more than 4 songs or so….
  • Cool Apps. For phones with browsers (almost every phone, nowadays), make sure to download Google Maps. It’s a must-have application, and very possibly the coolest thing you've ever seen in your entire life. Compatibility varies.

The FrankenPhone Dilemma

Bear in mind that most gadgetry is usually, and sometimes clumsily, just grafted on to the phone. The widgets will work, but don’t expect iPod-like Zen-ness from the design, or HD-quality on the display.


Summary

Overall, phones are as varied as your tastes. It's a crowded market, and that's good news for buyers – you have plenty of options and competitive prices. Relatively speaking, choosing a good cell phone is a snap. If you ever want a real challenge, try comparison shopping for particle colliders. Talk about a seller's market. And don't even get me started about government regulation. Make a few harmless inquiries about heavy ion accelerators, and suddenly you've got a dozen FBI agents to deal with. Honestly!

Blackberry for sprint
written by DyscernErika, October 10, 2008
Brad,

Any phone that is compatible with the Sprint network should be specified as being so. In the case of Dyscern phones, the name of the carrier is included in the title of the phone so you can easily see if it a specific phone is compatible with your carrier. Our inventory changes regularly so if you don't see the phone you are looking for right now, check back again soon. To see the phone selection, simply click mobile phones above.

Which ones for Sprint
written by Brad, October 09, 2008
Does anyone know which Blackberry I will need to use with Sprint. I know they dont use the SIM feature, so I doubt those will not work, but I am not sure.

Good read, I will pass this one along.
Yes, it will work
written by Dyscerm, October 05, 2007
Thank you for writing. Only Blackberries labeled "Nextel" will work on that carrier. It does not work on GSM phones.

On the MPx220s, same drill. They would not work with Nextel. Thank you.

will the blackberrys work with nextel
Yes, it will work

Thanks very much. Any unlocked Blackberry phone will work with the SIM. However, you will need to activate Blackberry service on Cingular (a simple phone call to Cingular will add it) to use the e-mail and data capabilities. Cingular will take care of the settings when they "bond" the unit to their service.
will it work
