t is for tdma, that's the first generation
i is second generation, not much diff tho.. sturdier antenna, that's about it
g is gsm i think, it's first generation
c is cdma, also first generation
p is the newest one, featuring PTT. but it's much thicker.
x i think this was supposed to be 3rd generation (before the p) but might have been scrapped.

howardforums would be another good place to ask this, i might have gotten some stuff wrong.
