yesterday i had to take some pictures of damaged fiber optic cable and send it to my supervisor. i took about 4 pics and tried to send all the attachements at once from the blackberry.
after like 10 minutes, i cancelled the send b/c the thing still wasnt finished.
not one picture was over 850k...so in total, at most, it was about 3.5mbs.
I have sent 4 meg attachments with no problems and regularly send 1 and 2 meg attachments. I do this regularly through my BES account and my personal Gmail account (non-BES) that is linked to my Blackberry
