Today for about 15 min any message i tried to send from the tmo 7290 went into pending for several minutes. Also I lost connectivity with my IM+. I was able to send sms fine. Anyone know what may of happened? I had a full GPRS signal.

The data servers, or components on T-mobile's data network, were likely congested or undergoing maintenance. It happens from time to time...

I had this problem from time to time. Pull the battery to reset and it will correct. Call t-mobile and let them know you're having a problem. You may also have to resend the service book.
