One of them main places that sells all types of iPhones is 02, nearly every type of iPhone that is available for purchase will be found on O2 as they are the main sellers. One can also look at places such as Amazon and Ebay for iPhones.
idk, but i have heard multiple things. i heard that it is alot of money, i heard it is inexpensive, but one thing for sure is that all my friends have iphones, and my mom wont let me get 1. She says the monthly cost is too much. :(
