I recently got the Blackberry Unlimited data plan for T-Mobile for my 7230 and tried the included AIM software. Everytime someone would IM me I got the following pop-up message:
IM from AIM. URL:http://188.8.131.52:80/?L&R=875978&service=tmobile
I couldn't figure out at that time how to close the AIM software so I had so many of these stupid messages that I received an error stating that my SIM was full.
I called support and eventually ended up totally reloading my BB. There are no messages sitting in any folder that I can see except for a single message created in Messages with this same information.
Now everytime I reboot my BB I get about 15 of these messages. This is regardless of whether wireless is on or off. I know I am not logged into the AIM software and haven't since that day. I have tried selecting each option (Open, Postpone, Ignore) but they come back each time I reboot. It was not so much a problem before but I am starting to use BB's automatic shutoff application and upon startup I get these messages.
