mckinney... you had replied to my post earlier about me receiving error msgs (e.g. "Protocol Error") on my Pearl when I try to sens SMS. And suggested to upgrade to .69 OS.
The one thing I noticed is when I do pop my battery, my SIM card door is not firmly locked. Could this be an issue to your knowledge?
