Well, my initial post was taking so long to type that I guess MacRumors signed me out, and I lost it all on the refresh. So here it goes again. I'd really appreciate it if someone could take just a moment to give this a once over and answer a couple of questions. I cam to MacRumors as this place is usually rife with members who really know what the **** they're talking about and these particular issues have never come up until I found out, recently, that I'd be moving. I'm moving very soon to Argentina for at least 6 months and I have a few questions regarding the steps that I could take to make sure that I'll be able to use my iPhone (or perhaps even a new one) in Argentina while I'm there. I have a couple general ATT and 3g questions so I'll lay everything out individually: 1) Does the situation still exist where the iPhone 3G, and I'd guess all subsequent 3g enabled iPhones, don't allow you to use the 3g service of any other provider or is that ONLY the case when trying to use the iPhone 3G with T-Mobile? 2) Getting more to the point, if I were to take the new iPhone 4 to Argentina (provided someone determines how to jailbreak it by then) and sign up with Movistar or Claro, and they supplied 3g service, would the 3g work with this iPhone, or is it locked to ATT in that regard? I had heard something about ATT's 3g being on a different frequency band. My mom is going to be purchasing an iPhone 4 in the coming weeks, which will most likely result in an extension of our contract. However, she may opt to create a new account entirely (if possible) so that our current service, which is currently out-of-contract, can stay that way. My question, which is actually a scenario that I've run through once very briefly, is this: 3) If she (my mom) were to purchase the iPhone 4, create a new account, complete with a new number (which I guess would have to happen), and then purchase another subsidized iPhone but NOT activate it (will Apple allow this again like they did with the first iPhone? Activating through iTunes at home? And why did they do this in the first place? I'm assuming it's because people would jailbreak before ever activating it.), could I then jailbreak that one, take it with me, and on the number that’s left open on the new contract, just give my old iPhone to my younger brother so that he can use that phone on that account? The out-of-contract account would just be cancelled since it's paid up. Is there something in that scenario (which I'd fleshed out a bit more in the past but after losing this entire post once, I've forgotten most of what I'd said) that I just completely missed or is it even slightly plausible? Another option would be to, I guess, buy the new subsidized iPhone on our current contract, extend the contract, buy another iPhone on it as well to replace my current one, jailbreak and move the new one, and just, once again, give my old one to my brother to use with my old number. Does ATT require you to register the phone or could I just, for example, get a used iPhone from a friend and swap the SIM from my current phone to his and use it with no problem? Because if that's the case it sounds like my initial suggestion would work fine (which is probably a sign that I've missed something). The entire aim is to obviously get the iPhone 4 at or near launch (won't be available in Argentina until August but probably Sept. is more likely and it'll cost far more than it would here) w/o the ETF from buying it subsidized and breaking the contract or the uber-expensive non-commitment price point? Would any of this work or is my best bet (assuming it's going to even be possible to jailbreak iOS 4) to pay that ETF or just pay $500-$700 for the phone w/o a contract commitment? ------------------------------ EDIT: Something tells me that the new micro-SIM "O.J. Simpson"s my entire plan.
