First problem is my gmail is constantly stuck on 4 new emails and when i do go to view my emails it says the connection to the servers been lost or something like that
Second problem is i try to open a pdf file with adobe viewer and it shows up as file path does not exist...
Which gmail view are you using? If you scroll down the LEFT pane to the bottom, there's links to Basic and Desktop versions. Pick one of those and see what happens.
Do you have a bb phone? I am guessing that most downloads are downloaded to the sd card on the phone. If that's not available, you could have issues. Is it just with pdf files or other downloads, too?
