I have it. Here is a half-assed review off the top of my head.
Pros:
The phone is hot, its phycially attractive.
The features are unrivaled for the price (up to 760 contacts can be stored)
No antenna (if you phone spends a lot of time in your pocket, antennas break fast)
GSM (its a new phone on the gsm network, lots of gsm goodies, and the US's gsm network is getting better by the day)
The screen - 65000 color screen, totally sick. the screen is the best i've ever seen on something as main stream as the T616
Battery life is good
Voice activated dialing, answering, and busy signal (i use these while driving with spirit and while at the soccer dome (phone in pocket, ear piece in ear))
Cons-
Memory is segmented. Picture memory will become full, and game memory will be almost empty, same goes with text messages and so on
Screen smudges easy (but is quick to clean)
Internet service on the phone has two ways of activation, most are easy to "bump" and if you are me you don't want to pay for internet service you never use, so i am always acidentlaly logging on (of note, i am not charged just for loading my home page, but i just don't like the service to be so easily reached)
Two tone - i wish it were a solid color, so i guess i should get a new case.
