Just restored my phone using redsn0w to get to iOS 5.01 preserving 1.59.00 unlockable baseband. I use At&t. Did not restore from backup. I setup as new iphone for a nice and clean install. However I am only getting 1 signal bar. I've restarted but that did not help. My wifes iphone 4 I restored to 5.01 with latest baseband (not unlockable). I used redsnow to jailbreak. Phone was setup as new. Her signal bars are just fine. anyone else? is there a flaw in the old baseband that was just not meant to be used with iOS 5.01?
