I've bought a 2nd hand 8800 from ebay, but the past owner claims he never used email on the device, or that if he did he doesn't remember setting it up. But, when i tried to create a new email account, and enter my IMEI and PIN, it says this: "Cannot create account. An account already exists for this Blackberry device. Please log in or contact your wireless service provider." When I enter my PIN and IMEI it says the same thing.
The former owner seems unlikely to help or do anything about this because he just keeps saying that he never used email on it. I've tried ringing my service provider, but they just said his (former) service provider has to deal with it. His former service provider obviously won't deal with me.
Any suggestions for how to fix this without needing his help would be really appreciated!
