I am awaiting for the new Blackberry 8800 to come out hopefully sometime in February/March 2007. At the moment, only Cingular will have it yet I read on cell forums that people will want to buy an "unlocked" version. Does this mean that you can use it with another provider? I currently use Sprint but they will not be getting the Blackberry 8800. So can I use this new Blackberry 8800 with Sprint, or will I have to switch to Cingular?
