iPhones in Hong Kong
I recently purchased an iPhone (the original version, not 3G) in the US and plan to take it to HK in a month where I will live for a year. Since I am leaving the US I am obviously going to forgo the 2 year contract with ATT. However the "unlocking" process is a little unfamiliar to me. I know I will be able to unlock it and use it in HK, but I am looking for a little more detail. If I have it unlocked in HK will I be able to use SIM cards from anywhere (ie China or the US) with my iPhone after I leave HK or will it only work exclusively in HK? Where would I go to get it unlocked? How much would it cost, roughly? What does the "unlocking" process entail (is it just adding software or is their hardware also involved)? Thanks in advance!
