I have an unlocked Treo 650 with a T-Mob SIM. This was an upgrade from an unlocked Treo 600 (The battery just wouldn't hold a charge more than a few hours)

I can send and recv SMS messages via the Message App. Works with SMS and MMS just fine. The problem is that from "Memo" or "Media" I am unable to pick send from the menu.

Any ideas on what is wrong? What prefs or files should I delete?
