recently I was given an iphone 4 that was locked to the orange network; it was my friends phone originallly but they forgot to unlock before cancelling their account and moving abroad ...... :/ have to be careful, because at the end of the day they still gave me a free iphone so I'm not ungrateful, its just I'm so tantalisingly close to having an iphone. anyway. after dealing with orange and their absymally shameful policies regarding unlocks and their atrocious customer services, I have decided I refuse to give them another penny of my money unless I can absolutely avoid it. I have three routes to iphone nirvana; A) I speak to my friend and try get it unlocked via the network, but that may prove tricky being abroad and all. B) I run an orange sim in the phone for 3 months and then they will perform an unlock for me.... C) I jailbreak it and use it on a network that is cheaper, and who has better customer service and generally I am happier giving my money to. so to my point: Going with option c, could I potentially run the jailbreaked phone for 3 months before briefly reverting to an orange sim to get my free unlock?
