i am using BB curve v4.2.2

i am trying to setup my account, but everytime i set it up, it decide that it is POP3 instead of IMAP
i am 100% sure that my email is an IMAP (i paid extra to have it IMAP), and i am using it from my laptop as an IMAP.

how can i manually change it to IMAP ? (there is not option to do so)

Go to GMail site for instructions on how to manually do settings on blackberry for IMAP gmail and enter the settings for your email.

At least that would help u get into the manual settings mode...

i have an email from my domain which is registered with Register Domain Names at Register.com | Domain Name Registration & Web Hosting Services

i paid the extra fees to make it IMAP, but blackberry setup doesnt recognize it as IMAP, only as POP3

what shall i do?

Go to Gmail site which explains how to set BB up for Gmail's IMAP.
It will explain how to force bb to accept IMAP settings instead of automatically going for POP3 settings.
