Can you get wifi to work? You will need to restore your phone and do the jailbreak again. Unfortunatly restoring your phone will update it to 4.2. You will need to save your SHSH blobs in cydia by pressing the 'make my life easier' button so you can then roll back to 4.1. Do this before restoring in iTunes or you will be stuck on 4.2.
OK understand that, wifi is working, i have saved my shsh's on cydia and through tiny umbrella. Probably wont restore it until the new 4.1 unlock is out (new to the iphone so dont want to mess up things) But why does it show the network & carrier as "Not available".
Also this iphone came new and sealed on FW 4.1 and Baseband 02.10.04, when i first did the jailbreak on Monday, i did not make a shsh save. Im still on FW 4.1 and baseband 02.10.04, and so when 4.2 was released everyone was saying, save your SHSH file immediately so i have done that. So is this ok, (ihaven't messed anything up by not saving them when i first jailbreaked it?)
Also if i wanted to restore to what it was out of the box (FW 4.1 and baseband 02.10.04) and without the jailbreak, how can that be done. (so at least i can see the vodafone carrier again and get peace of mind)
