I just bought a 3gs it was on 3.1.2 and modem was 5.11 I got home connected with pc downloaded blackrain and everything went well, saw the geo hot logo restarted. then when i saw the icon where u click install cydia and snow for the unlock. I did that then i insterted my sim card, it said searching so I knew i had to turn of the 3g in order for it to detect tmobile. I went to settings then the phone just FROZE! after 30 mins nothing happened. i pressed home button and power button did a reset. now its stuck on the apple logo. anybody know why? any help would be greatly helpful!!!
PS: its under 90 days warranty
