Hello, Please i dont want any replies about searching for other threads and all that because half the time they are off topic. I have jailbroken (not unlocked) Iphone generation 1 currently living in the U.S under the AT&T network. I am going to London next month and I wanted to be able to use at least calls local in England, and also to u.s.a, email, possibly text messaging local in london and to u.s.a . Do i need to unlock my phone and how do i go about doing that, and dealing with a sim or what ever when i get to london? Any options? Also, with the texting, see i can buy the international plan but i dont want my friends from here getting charged international rates to text me there. Any ideas? would really appreciate it. Im not very familiar with using the phone abroad.
