Just a quick heads-up: MuscleNerd just announced that ‘ The 4.3.1 issues (signal bars, etc) are fixed, but need a few days to test all devices + FW (again: not a new unlock! ) ‘ . This won’t be a brand new ultrasn0w, but an update to the existing one which will allow already unlocked iPhone users to update to iOS 4.3.1.
Remember that, a couple of days ago, when the iPhone DevTeam released the new PwnageTool for iOS 4.3.1, but we also got a big fat warning: ultrasn0w users don’t update yet! We need to first release an update to ultrasn0w that fixes some incompatibilities when FW 4.3.1 is used on the older basebands supported by ultrasn0w. And remember once we do fix ultrasn0w for 4.3.1 (we’ll announce it here and on twitter), you must only get there via a custom IPSW from PwnageTool, Sn0wbreeze or xpwn! Don’t ever try to restore or update to a stock IPSW, or you’ll lose the unlock!
Apparently, ultrasn0w will be update in a few days and we will keep you updated. Stay tuned….
