The QWERTY keyboard is similar to the other Curve models. The buttons are on the small size, so users with larger thumbs will probably have some problems with it at first. Since I have small hands, I had no problems typing messages on it.
The Curve 8530 offers synchronization with BlackBerry Enterprise server, with support
for Microsoft Exchange, IBM Lotus Domino, or Novell GroupWise, to
deliver corporate e-mail in real time. BlackBerry Internet Service also allows you to access up to 10 personal/business POP3 or IMAP4 e-mail accounts.
