the better IS NOKIA BLACKBERRY CURVE
CARRIER CINGULAR I own the Pearl and the Curve!!
I've been using the Curve immediately for 4 days! I absolutely LOVE it!! But I miss my Pearl too. My daughter is presently using it.
BlackBerry is the best phone I've ever owned!! I know most ppl say its "corporate" but IMO I found NOTHING corporate in the region of it. Except for email I suppose. I use it for everyday use, phone text transcription reminders alarm MP3 player Internet. Its the most awesome device I've ever owned!
The difference between the 2 is the basically the peak size the keyboard which on Curve is QWERTY and WiFi. I'm sure theres a few other things but that's what I've notice and like nearly the Curve over the Pearl. =}
