I have been looking for any information on the service discontinuing by ATT.
I even looked on their forum page. I hope they don't because I don't like the android and iPhone because they force users to upgrade by dropping support and blocking apps unless you have the latest OS from them. I tried to do an upgrade on a android phone I had and it was blocked for updates. a very simple message from google was that the phone was no longer supported. Apple uses the same method. Nice way to sell more phones. force users to dump them in two years.
if you have a link that tells users ATT is dropping service please post it.
