Be patient with me gang--I know just enough about this stuff to make myself dangerous. I need advice: I know the question of whether to buy the AT&T or Int'l version for American users has been posed. I have the same question, but from a different perspective of different needs. Here's my issue: My wife and I have a family account and are looking to renew; however, for the next year, both of us will be spending a lot of time in Europe--Spain, Italy, and the UK mainly. So fundamentally, I want a phone I can use well in both locations. Spec-wise, we prefer the AT&T version, but what we don't know exactly what's to be gained or lost by using the Int'l version and want to make sure we avoid any potholes. Hoping your can help. I think our essential questions are these: 1) If unlocked, can the AT&T version be used in Europe? Should I expect any problems or decreased usability of any kind? For instance, will European networks treat the phone just as the Int'l One X, or will I experience slower or less frequent data? 2) Suppose we bite the bullet and use the Int'l version. Should we expect any network issues--in particular, a hard time finding HSPA+ use? Will data be slow or hard to get? 3) What do you think the chances are of getting AT&T to unlock the phone, given we've been customers for 4 years? Alternatively, do you think the bootloader issue will be solved, or hacks will be created to unlock the phone? My understanding--and correct me if I'm wrong--is that the AT&T One X should work basically the same as the Int'l version abroad. The real problem will be getting the unlock from AT&T, which presently seems like a bit of a nightmare. Thus, if this remains a real problem, getting the Int'l version--despite the extra $$--may be the simplest solution. Thank you all in advance. Any help you can offer would be greatly appreciated.
