I think the blackberry itself could handle as much if not more than a Droid.....
...As I understand it the issue IS the BB internet service.
...A chain is ONLY as strong as it's weakest link.
This is why you can open and read a pdf attachment of 4.5mb or larger on a Droid or an iphone...
...But you can't open and read one on a blackberry.
I experienced this first hand when I was the only one in a group of people who got the same email....
...And I was the ONLY one who couldn't open and look at the architectural plans PDF that was sent to all of us.
...I was the only one on a BB - the others were on Droids or iphones.
Yeah that's one thing I don't understand is why everyone says BB is superior when it comes to email. Actually BB has enough shortcomings imo with email!
