I just got mine from verizon and it rocks! came with 4 themes in both menu and icon styles that you can simply change up in options.
I use both http and pop/smtp email accounts and they work great!
Heres the differnece:
you will get one email address like
you will have up to 9 more pop/smtp or http accounts you can add to your BB.
when you get your pop/smtp addresses setup, your BB will poll your pop server every 15 minutes for new messages whereas if someone sends you an email to your
address it is received almost immediately (within 1 minute) of the sender sending the email.
There is no way that i know of to force your BB to check for email at a faster increment that every 15 minutes for your pop/smtp email accounts.
hope that helps
