The Blackberry OS's have improve a lot over time check out crackberry.com and see for yourself. I've updated mine from the original tmobile os to the newer one.
Are you talking about the 8320 or the Pearls? Going to check this out myself.
[edit]
Hrm, I'm on 4.5.0.81 and the new one is 4.5.0.124.. hrm.. Wonder if its worth it. Still dislike the memory leaks on the phone. Oh well, best phone I've had yet
