Anyone know where to download an AIM app and a MSN app? Somehow they got deleted off my blackberry. Its weird. I've been looking like crazy.

just go to the blackberry home page on your BB browser, they have a link to the IM clients there

I only see links to Yahoo, Google Talk, and BB Messenger on that site. No AIM or MSN.....

Poetic, what OS version are you running? AIM and MSN should be part of the 4.5 OS install. If you are already running OS 4.5, run Desktop Manager, then run the application loader, and see if AIM and MSN are in the list of available programs. If so, check their checkboxes and install.

Check over in the General section - there's a thread about loading the service book files for T-MO and AT&T. Its under AIM ICO.....
