Just recv'd notice from AT&T that come May 15th my Treo 650 will no longer be able to access their wireless network. They write that due to network upgrades, "Unfortunately, a small number of customers will no longer be able to use their phones" after that date. Does that mean they will no longer support GSM? As long as they still support GSM can't I just tell them I bought a new phone? If I understand correctly this means that AT&T is discontinuing ALL GSM 850 - 1900 traffic and that just seems so unlikely. Then again it would mean forcing a bunch of cheapskates to choose to either spend more at AT&T (good for them) or making people reevaluate having a cell phone at all or switching carriers.
