It started yesterday when iPhone users on AT&T’s GoPhone month to month plan started getting errors when trying to connect to the internet via the EDGE network. At first, this problem was blamed on the 1.1.3 iPhone update. In a post on TUAW:

“You are not subscribed to the EDGE network” is the message facing the affected users. Subsequent calls to AT&T have resulted in a mixed response. They’re aware of the problem and generally offering a change of plans as a solution. The options seem to involve restarting your monthly billing or paying by the kilobyte, which is likely not a prospect most previously content GoPhone users are looking forward to.

But then it was discovered that the problem was not the iPhone update but rather a crash of AT&T’s server:
“Despite earlier assumptions by myself and users who first reported the problem it is not the 1.1.3 update that is causing the GoPhone problem, but rather an apparently coincidental server crash. AT&T support is offering a limited quick fix for some users, but is working on a long-term solution.”

It is not surprising that people jumped to conclusions that it was the iPhone update. We’ll keep people posted on what AT&T is doing to fix this problem once and for all.
