I bought an iphone from my friend... but i dont enjoy cingular.. if i get a untried plan can i get it beside the free phones they give you and put that sim card contained by?
Answers: If you choose AT&T (formerly called Cingular), you call for to have an Iphone plan or your iphone won't work, unless you unlock your phone. The iphone plan costs $20 more. When I originally get my iphone, I got the free phone, and the iphone at alike time. I can use both phones with the iphone's sim card. I consider the same will work for you, but you should ask something like at&t upgrading policy.
Alternatively, you can ulock your iphone, and use it on another carrier (such as tmobile).
