Ok, with gprs and not GPRS you'll never receive a service book, what you are going to have to do is install the T-mobile UK handheld software package, it's fairly simple to turn the .de device into a .uk device with that.

Until you get GPRS you won't be receiving any service books, this could also be because your T-mobile account still isn't provisioned for the Blackberry Data service.

pop over to www.rimroad.com otherwise where there are other UK users who can guide you to the software...
