Well, I went ahead and dl'd 4.1gm, and installed it. Everything went smoothly, until I noticed that 3G data had stopped working. The phone was jailbroken on 4.0.1 before, and I knew I would lose the jailbreak, but didnt think there would be problems with data. I have tried resetting network connections, and restoring from backup, nothing seems to work. All I have not done yet is to restore it as a new device, simply because I don't want to loose all of my data. Any ideas?
