I have had a little search but kinda find a situation exactlly where this has happened.. My 3G and wifi have been working fine, but today in the afternoon both just stopped working.. I have an iphone 3G on 3.1.2 unlocked with blacksnow and jailbroken with blackrain. I have backed up my shsh on saurik's server so was thinking about restoring back to 3.1.2 and just doing it all again but its just such a long process reinstalling everything and etc etc etc which i would really rather not go through!! is there a common fix or would i have to restore to 3.1.2 using help from this article: http://www.ihackintosh.com/2010/02/downgrade-iphone-3gs-os-3-1-3-to-3-1-2-with-cydia-shsh/ i really really need the unlock as i dont have any other phones and am stuck at university! any danger to the unlock is not worth the risk! any help much appreciated guys, cheers.
