unlocked iphone 4s question
Hey everyone I have a question about my jailbroken at&t iphone 4s
Im going to Denmark in a few weeks and I will be there for 3 weeks, i was planning on unlocking my old 3gs and using it over there but i was wondering can i unlock my jailbroken 4s and use it overseas with another sim card? Ive jailbroken all my iDevices but when it comes to unlocking and what i can and cant do with them Im new at it. Im still on a 2 year contract with att so im not sure if i can just call them and tell them im traveling overseas and to stop my service for a few weeks and then just pop in a another sim card and use my 4s. Thanks everyone and sorry for the long post and if i posted in the wrong section please move it i wasent sure where to post!
