i was reading redmond pie and came across this. http://www.redmondpie.com/jailbreak-ipad-4.3.4-using-pwnagetool-bundle-how-to-tutorial/ What does difference between the ipad2 Wifi and ipad wifi+3G? I thought as long as you have the blob saved then you can restore to that firmware. "if you have updated your iPad 2 to iOS 4.3.4 by mistake then youve lost your jailbreak for good, if you have a 3G iPad 2 that is. Unless you have a Wi-Fi only iPad 2 and have saved your SHSH blobs for iOS 4.3.3, then you can smoothly downgrade and jailbreak using JailbreakMe 3.0 on iOS 4.3.3"
