My friend and I both have the Focus (on ATT) and he used the 78er to force update, and everything was going good for about a month until his start screen went toasted. He was and is under contract and that voided his warranty. He isnt a happy camper right about now. As for me, my contract ended in March so I am looking to go back to Android.
Im getting sick and tired of these "promised" updates by Microsoft and ATT but never get them. It took me 10 months to get Tango.
