I just bought a used Blackberry 7280 that was used with Cingular, however I have my phone service with Sprint. I was just wondering if it was possible to have it re-programmed through the store, to work with my existing plan with Sprint? Or am I stuck with getting a seperate service with Cingular in order to use the Blackberry? (I mainly want to use it for text messaging). Thanks

No, not possible. Cingular is a GSM network where as Sprint os a PCS network, completely different technologies
