anyway, i recently upgraded my OS on my BB Curve for tmobile to 4.5....everything works except for my AIM. it says "Service not enabled for this handheld"
This has been covered before. It wont work because the OS you upgraded to AIM doesnt work for your phone. BUT, the .44 upgrade for AIM 2.0 works PERFECTLY :-)
Differences?
Never been on old aim, but I do know that you can have ALL your buddylist and transfer files (and yes, even full mp3s to one another).
Yeah its still in Beta, but hopefully soon they give us an official release cuz i love 4.5 over 4.2.
and I haven't experienced any lag, i get all my messages within seconds as if I was on a computer doing it.
