i never jailbroke mine though, the speaker just stopped. buttttt i successfully bricked my phone !!!!!!!

i did this:

1. restored to 3.1 beta
2. put it in dfu
3. attempted to restore in itunes
4. unpluged
5. error stuck at logo!!!

then i threw it cause i hate it (pointless)

anyway at least i can get a phone that i can hear ringing now


EDIT: heres a screenshot of itunes error and credit goes to some guy on modmyi
