hey everyone , i just upgraded to a blackberry curve sunet from tmobile. im comming from the sidekick 3 and im in need of some helpfull advice. So im all set with the data plan and ive added 400 sms. My biggest concern here is that i use ims frequently so i was looking around for a im client and found jive talk. is this a one time fee youll be charged or is it monthly? lastly is there a way to customize your theme to make your own? and do tmobile blackberrys carry the blackberry maps feature? i havent gotten my curve yet , hopefully in 3 days but i am excitedd!!
