| | Re: NEED: OS / Service Books for Storm2 9550 unlocked w/out data plan
As far as I know, in order to get the service books from your carrier (T-Mobile) you have to have a BlackBerry data plan. The service books do not come with the OS. They are two separate downloads, and updating your OS can delete your service books. That's no problem if you have the data plan as they can be sent right back to your phone. I have no idea how you'd get them onto your phone otherwise.
