Update your iPhone OS 3.0 beta or your terminal will lock automatically
Saturday, May 23rd, 2009Apple iPhone OS 3.0 beta firmware has a time expiration, and if you don't update regularly with new releases your terminal will lock, and that's what happened to three of my friends yesterday.
The truth is that apparently Apple does not mention anything about it on the iPhone Development Program website, and if you don't update to the new beta versions, after a couple of days your iPhone will stop working and you'll see the famous "Connect to iTunes" screen.
The solution is to download the latest firmware version and do a normal update/restore with iTunes.
