I received the following question in our contact form:
My boyfriend bought a used BlackBerry and does not have a manual for it. He
does not know the series number. Is there something to push on the phone that
tells him the exact series number so I can order him the appropriate manual?
If you have a BlackBerry but aren’t quite sure what model number it is, all you have to do is go to Options –> About… You will see not only your exact model number, but, the OS version that currently running on the your device. Once you know your device model, head over to http://us.blackberry.com/support/devices/. You should be able to find and download any device specific documentation that you may need as well as any updated software for your device.
