Good Luck! -Flame ******************************************* As far as having less than 900 messages...its for speed and storage space. The BB internet is only so fast...generating those messages (had they not been stored on the phone alread) would take quite some time. Also, BB don't have unlimited space, so storage is an issue. Depending on the type of e-mails, 900 messages could easily go over the 64MB most BB's have. Hope this helps! -Schmidtw
