so the GPS has to be activated through Tmobile? I thought the 3G had it in the phone.You can do a 3G in like 15min. GPS will work as long as u get a gps activated 3G plan with tmobile. PM me and I can email you links to the software and bootloaders you need.
The apps you can get through Cydia are cool but as mark said unless you are a programmer you can get most of them through the app store. If you have any interest in programming c/obj. C apps then there are compilers and such available that you can't get through apple. Also if you jailbreak you can change what you phone looks like with themes.
there has to be a way to make it work with a jailbroken unlocked iPhone.you need the gps plan thru tmobes activated i believe
sweet!We just did mine and there is a lot of cool stuff you can do. Like so far 123spoof is my favorite. You can call anyone from your phone but you can choose whatever phone number you want to appear. So for instance I called a friend from another friends number and messed with him. If they have the number in there contacts it comes up with the persons name.
