The new iPhone has long been rumoured to be ready for superfast 4G/LTE mobile broadband.
Apple ran into trouble with the third-generation iPad earlier this year when its SIM-card equipped cellular version was marketed as a 4G model worldwide even though it was not compatible with 4G frequencies used in Australia, for example, and the UK and most of Europe are yet to get official 4G services.
Obviously the best way around hitting the same problem with the new iPhone is to make sure it works on all 4G frequencies commonly used in various parts of the world, although it is a big technical challenge. It could be that there will be slightly different versions, tailored according to what LTE bands are used in or around the region where you bought it, although that wouldn’t be popular with long-haul travellers.
The UK is due for a 4G service from Everything Everywhere (Orange and T-Mobile) later in 2012, with others following in 2013 across a wider range of frequencies.
Expect more to be revealed once the new iPhone is unveiled on 12 September.
