The 3G version of the Apple iPhone was released in July 2008 as an update to the original 2007 model. Apple decided to launch the 3G model with a bang and it was given a simultaneous release in 22 countries on July 11th, a decision which caused different problems in different parts of the world. In the USA there was a problem with activating the new phones on the networks, for which Apple blamed the phone operators and vice versa. To make matters worse owners of the original iPhone were sent updates which could not be activated either, leaving them without a phone for several hours. In the UK long queues formed and stock levels were a problem - the Apple store on Regent Street announced at 3pm that it wasn't selling the phone to anyone not already in the queue and eventually police were called to restore a bit of order.
The improvements brought by the 3G version of the iPhone were 3G internet connectivity, assisted GPS (the 2G had none), Geo-tagging and third-party application integration added to the camera, Longer 2G talk time (10 hours instead of 8), Longer standby time - (300 hours instead of 250). 3G talk time or internet usage is around half that - 5 hours.
