AIM for BlackBerry (built by AOL) replacing RIM-built AIM client
With the recent Native BlackBerry IM clients updates, some of you were questioning why AIM was not included in the update.
Well, it seems the reasoning behind this is that RIM-built AOL Instant Messenger has been discontinued. Don't worry, you'll still be able to get AIM on your BlackBerry, as AOL has built their own app.
Beginning October 28, 2011, the AOL Instant Messenger (AIM) for BlackBerry® smartphones application which you may currently be using is being discontinued and will no longer be supported. You may continue to access AIM service for your BlackBerry smartphone through a new AIM for BlackBerry® application built by AOL, which includes new capabilities such as letting you stay connected with your AIM Buddies and Facebook Chat friends while on the go.
To update to AIM for BlackBerry® built by AOL, please visit: Free AIM - Download AIM - Free Apps from BlackBerry App World
and follow the on-screen instructions. To remove your current version of the AOL Instant Messenger for BlackBerry application, please refer to the support article at KB26171-Discontinuation of AOL Instant Messenger for BlackBerry smartphones
Please remember to install the new AIM for BlackBerry® application built by AOL before October 28, 2011 in order to continue sending and receiving AIM instant messages on your BlackBerry smartphone.
