Ok, here is the question and it is based around the blackberry pearl and the blackberry 8820 phone.

Can you turn off the phone function of the blackberry and keep the data/email side of it on? I ask this as I do alot of traveling on planes and would like the ability to be able to do e-mail and stuff but not have the phone transmitter on -or- can I turn off all transmission functions of the blackberry so that I can at least read and respond to e-mail messages and when I land and can turn it back on, do so and then have it resync and send all the messages I just replied to?

THanks.
