There are some points I do not fully understand about this thingy.
I want to know if there are any significant problems that would await me if I want to upgarde some (ebay bought) iphone 3G with FM 2.2.1 or older with the 3.0 OS.
I need to buy some unlocked over ebay. Although my current provider offers an iphone their price is ridiculous. This phone is never worth that much money.
Also are there differneces between these unlocks. There are some who claim to offer officially/legally/factory unlocked phones. Is this worth something or just some nonsense.
I want to be able to use it in Austria and the United States. But I don't need 3G at least not yet. I have almost 95% of the time wifi access. So I will not pay for expensive 3G internet.
