Depending on where you buy your iPhone 5 (i.e. which mobile phone carrier) you will get different models with varying tec specs (LTE support). You will also have different iOS 6 features available (services like Siri), depending on the country you use the iPhone. At worst your iPhone will only work with the LTE network of some providers. (There are 3 different iPhone 5 models at the moment). So better make sure you know which one you’re buying! For a break down of the LTE capabilities of the iPhone 5, refer to this official Apple site. If you want to find out which iOS 6 services are supported in your country, make yourself familiar with Apple’s iOS 6 feature availability list.
