Do you guys think it will ever be possible for the verizon or sprint iphone 4s to be fully unlock so it will work domestically inside the united states (AT&T or Tmobile). i know right now theres the global unlock for verizon and sprint, but i dont travel much =/. if the software unlock comes out for the iphone 4s i would be truly grateful. just in case verizon dies or goes out of buisiness...
