Hi All, I want to check if its true that there are separate iPhone models/different qualities for US and other countries? Why i'm asking is because i'm from asia and there is a reseller who says that an iPhone from singapore will cost about 15 USD cheaper than a iPhone brought from US. This is kinda new to me and im not sure if this seller is lying to me. "All Apple iOS devices have a model number which looks something like this: MC605LL/A. The MC605 is an iPhone 4, black, 32GB. You can find these numbers on the Models page. The two letters behind it, LL in this case, specify the region code. " Thanks for your feedback!
