What do you mean, "send files from your computer to phone"? What are you trying to send? Are you trying to do this via Bluetooth?
You can take videos if you download the 4.5 OS. It's not officially out yet, so be careful and make sure you know what you are doing if you decide to upgrade.
You can change the LED colors with a 3rd party program.. I forgot what it's called though, do a search.
And no there is no way to change the color of the trackball with software. You'd have to take the phone apart, there are guides on the forums somewhere.
yes im trying to do this via bluetooth, i can send the files from my phone to my computer no problem, but when i try and send it from the comp to the phone it says
"Service File Transfer not found on device Blackberry 8320"
i have no idea what that means, i have tried to send diff types of files and nothing
