Just bought a 3GS today, running 3.0 fw. Jailbroke with Redsn0w worked a charm. Until someone called me. Phone vibrates but does not sound a ringtone. Checked all the settings, and they appear to be ok, and phone is not in silent mode.

If anyone has come accross this also please post here, and if anyone knows a solution to this please be sure to let me know. Thanks.

About to restore phone to factory settings to make sure it's not a hardware issue. I dont think it is but I will double check.

Cheers
BB
