hi I have iPhone 4 32 gb running OS 4.0.1, jailbroken (Limera1n) and unlocked (ultrasnow). I accidentally reset my network setting, the phone rebooted and when it came up again my unlock seemed to be gone: I gent no signal bars and can't make calls. "voicemail" key in phone app is dead. in general\network i don't have "carrier" at all but in "about", however, it does still mention my local carrier under "carrier". I tryed re-installing ultrasnow on cydia, didn't work. carrier bundle missing? limera1n-ultrasnow collision? please help i need the phone! thanks!
