Hi,
am new to apple, but a mate of mine has given me his old o2 iphone 5c

I want to use my talkmobile sim in there but the iphone will not let me, think its still locked to o2?

Can Jailbreaking it get shut of the o2 lock?

if so how (I have tried!)

the phone is not black listed, and works fine with the old o2 sim, can someone point me in the correct way how to get my talkmobile sime to work??


Thanks!
