Hi, I was happy with my jailbroken iPad2, 4.3.3 until I installed the "critical update" that Cydia prompted a few days ago, while I was on holiday. I saw Comex twittered about it and figured that it would be best to install it. Since then, my iPad refuses to connect to my 3G operator with the message "Restricted Network". I searched for a solution but found only very old posts about similar issues on old jailbroken iPhones. Can anyone point me in the right direction for a fix?
I have a fairly recent backup made in iTunes, one made before installing the upgrade. Can I safely use that to return to the previous state or will Apple do something nasty if I try? I also have an SHSH blob saved for 4.3.3, but I understand that this isn't useful yet...
Of course, I would prefer not to restore the backup since I have a lot of new data on my device. As in photos, texts, map bookmarks, etc that I would have to salvage before I try anything drastic.
I have installed one or two apps from Cydia around the same time I lost GSM as well, I think it was the demo of iFile and the free Safari download plugin. I don't see how any of those could be to blame and assume that it was the JB update that messed things up.
Edit: Drat, I might have posted in the wrong forum as this is a question and not a tutorial. I humbly beg a moderator to move it for me as I can't find a way to do it myself. Thanks in advance.
