Hi guys, I live in Brazil and iPhones are extremely expensive here. Also, the iPhone 4 wasn't even launched yet, and I was thinking of buying it when traveling abroad. If I buy it in Europe unlocked, it will cost about 500€, which is still very expensive. So I was thinking about buying it in the US, and I'd like some advise on that. My idea is to have an american friend of mine buy it regularly with the least-expensive at&t plan, then simply cancel the contract (and pay the fee required to cancel it), so that I can take the iPhone here with me. Questions: how much does it cost, more or less, to do all this? I can't find this info anywhere.. and also, is there any info on how the hardware is gonna work outside the US? (Wi-fi, gps, cellular network, etc..) We have decent 3G networks over here, but I'd use it MUCH more on wi-fi that anything else, so if the 3G network doesn't work perfectly, it's not an issue. Thanks a lot in advance!!
