Hello, I just got an HTC Hero (Sprint) from eBay and I want to know if I'll be able to use it with my local carrier; if I unlock it. Or should I install another ROM to it (Flash it). I'm from Morocco btw. Thanks. EDIT: I recently unlocked Blackberry Storm 9530 (Verizon, CDMA) and its working fine with my carrier, so should the HTC Hero (sprint) work aswell?
