Hey, and thanks for adding that important note. Just to reinterate what Suzy stated, the instant messaging apps work differently on 3G Smartphones than on the 3G Multimedia phones. Thanks, Suzy, Kudos for reminding others who may not be BB users but may be other devices users that just may be reading this thread.
Thank you Doc! The answer, in this case, really does depend on your device....and I think that's where some of the confusion comes in.
Instant Messaging can use both data and texts....which one depnds on your device and how you are accessing the AIM and YIM apps. Are we clear now?!?
