Hi, three days ago I decided I would finally update from 4.0.1 to 4.1 on my iPhone 3GS (new bootrom) - because I had save blobs I could do so. - I installed 4.1 via iTunes and locally stored SHSH blobs - jailbroke with limera1n - installed Cydia and AppSync 4.1 - restored with iTunes Things were restored perfectly, apps work, and so on. EXCEPT I do not have service. GSM tells me "No Service", therefore no Edge or 3G connection either. WLAN does work just fine. This is a lockfree iPhone from Italy, so I don't need any unlockers. I tried restarting, re-inserting the SIM-card (which recognizes my PIN correctly), resetting ALL network settings. I have even installed "Signal" via Cydia, which actually actively restarts commcenter .... Any ideas?
