I know the current iPhones can work on all 4 GSM frequences (850, 900, 1800, & 1900mhz). But I've read that in some countries 3G data runs on 2100mhz (either in Europe or Australia, I forget). Anyway I was wondering how many frequencies would be needed in the phone for Apple to created a device/phone that could be fully used for 3G everywhere. I wonder if they would try to create such a phone, or if they would make 3G phones that were customized by 3G data freqency by country. Is it possible to have a phone with so many differnt antennas inside? Would that much hardware play together nicely?
