Well, i guess i have my answer.
Im actually familiar with the BB plans in my carrier and what i know from the blackberry and the OS is from watching a lot of reviews and read.
I wont use email because we use mostly sms because they are free for the same carrier...
Anyway, i only considered the BB because it was cheaper for me, but i don't a device that i won't be able to take full advantage of...
Thanks for the help
