I urgently need to update from iOs4.3.5 to iOs5.1 today as I am going away at the weekend and there's an app I need which is iOs5.1 only. I don't want to brick my iPad though and will have to leave it if it's going to take too long. I will need to update iTunes to 10.6 manually as it always fails otherwise, then backup, update and restore.
Can anyone give me a ballpark figure of how long this should take - 2 hours, 10, 24? If it's going to take too long I'll have to leave it as I'd rather have it as it is than not at all. Thanks for any help.
