2Gb microSD from Kingston works like a charm. At least it is enough to keep a cpl of pics from the family & 250+ songs for use when flying..tis all i need.
As for time messages are kept on the BB, i am not 100% sure on this, but believe that it was our IT guys administrating the BES that set ours at 21 days. After which they are deleted from the BB. However they remain
indefinitely on Lotus Notes until cleared and DVD'd as an archive.
..actually, I'm glad it is only 21 days. A guy could wear out a trackball if they went for a year or so..!!
cheers,
