Hey everyone...So I bought a Blackberry 7750 on EBAY and when I got it wouldn't guess it the phone screen and network was Sprint. Is there anyway to change the network to verizon. When I check the 'options' I went to Netwk and it said Sprint. Before that Icalled Verizon to have them activate the phone and they informed me the EPC or whatever its called wasn't compatible....Any help on this....my other verizon phone is slowly dying....
