I just traded with a mate for his iPhone but it's network locked to Telstra. If I jailbreak it will it unlock it so I can use my provider? Also if I jailbreak it can I still use the app store as I have a few apps I need, thanks :)
  Added (1). My mate bought it 2nd hand off ebay, doesn't have contact with the seller either :(
  Added (2). Also ios is 6.0.1
