my blackberry won't let me see all my emails. i know that i emailed myself a wallpaper from crackberry, and i received the email and downloaded the wallpaper, but now the email isn't in my messages folder. i thought i remembered seeing it in a junk folder maybe? but now i can't find that.
There is no junk or deleted folder on your bb. You might have saved it though. From your messages screen, hit the menu button, the select view saved messages and see if what you're looking for is there.
