I did the text, I got this response "Due to past due balance and other reasons, an upgrade is not available. Payment will make full retail pricing available. Use *PAY to check your balance and pay your bill from your phone or visit att.com/wireless. An upgrade may be available on 2/22/2011. Does this mean I can still get the early upgrade price of 400/500? We have a family plan. 5 iPhone 3G's on release date, upgraded 3 of them to iPhone 3GS on release date (paid 300, 500, 500) respectively.
