I have 2 7100i both of them don't have the service books because they were from an enterprise account and were wiped before I got them. I know of someone on another forum who is using his BB with boost mobile and has the service books left on his device since he once had the bb plan on it. He still has the books for "Provisioning," "BBIMConfig" and MMS. I have nothing I can't even use google talk it says service not enabled for this device. It is possible to back up the service books with BB desktop manager so I at least want to try it otherwise 2 7100i up for grabs, iPhone here I come. I can use AIM on my phone and BB messenger works. I have an unlimited data plan from boost also unlimited text messaging. I at least want the browser somewhat functional so that I can view pictures and download files.
