I’ve been on 4.1 for a while because I’ve been too lazy to update my iPhone 4 to iOS 4.2.1. I just got this SMS from AT&T a few minutes ago.. It seems like AT&T is tracking what firmware everyone is using on the iPhone and wants people to update. I’ve never gotten a message like this before.
AT&T Free Msg: An important software update is available for your iPhone. To update to iOS 4.2, connect to iTunes and follow the instructions.
