Since a very long time, I wanted to get a phone that is actually just a phone. It should:
1. Look like a phone (not a brick)
2. Synchronize with the computer (Mac) without any special software
3. Have bluetooth
4. (if possible) NOT have a camera.
You will find tons of phones with the above features for GSM (T-Mobile/Cingular), but there are none for Sprint. Sprint is very notorious in crippling the features from their phones. So recently, I needed to get a new phone, and found the perfect one: the Sony Ericsson T608.
This phone was sold by Sprint 2 years ago through phone sales. You can not buy it online or through the normal sprint stores, but if you call them and complain that you want a bluetooth phone, they will send this one to you. This phone has everything that a phone should actually have, and it seems to be untouched by Sprint, so has its features intact. I had decided to leave Sprint if this phone was not available.
As this model has been discontinued (rumors say that Sony made only 10,000 of these), I bought a used one from eBay. Turned the phone on, clicked the bluetooth button on the mac, and its up and working! All my contacts, calender, etc. is perfectly synchronized. I can also send files (ringtones, pictures, etc) through bluetooth to this phone, so no need of using random software. Finally there is peace in the Sprint World.
Well, sprint just released the "Samsung Blade" (a motorola razr copy), which claims to have OBEX support. Its not added to iSync as for now. And its not exactly cheap. Till then, T680 Rocks!
