Ok guys so I don't know all that much about cell phones but I've decided that I really need a way to keep synced with my macbook so that I can remember what I am supposed to be doing. I saw how the iPhone syncs up and it looked awesome but I don't really want to spend 500 or 600 bucks on a phone just so my calendar and to do list can be at my fingertips.

Heres all I really need:

A phone that is compatible with iSync

Any form factor
bluetooth a plus but not neccesary
mp3 playback good but not neccesary
decent camera maybe like 1.3 MP
A nice screen that is good enough to easily manage a calendar
A keypad that is good enough to handle entering to dos and things in easily (regular or QWERTY is ok)

Thanks in advance
