-- but we still have a lot of questions. When will it launch? Where will you get it? And will next-generation mobile phone speeds leave a gaping hole in your wallet?
We put your questions to the first 4G phone network, EE. Formerly known as Everything Everywhere, EE was formed by the merger of Orange and T-Mobile,.
The iPhone 5, , HTC One XL and are , with the and a 4G version of the to follow later in the year. You can buy them now and switch to 4G when the LTE network launches, although that means taking a gamble on how much 4G will cost.
CNET UK met EE network expert Tom Bennett to discuss the coming of 4G. Press play on our video above to see what EE has to say -- although EE is staying tight-lipped about a launch date and details of pricing, we did learn that 4G could improve your phone speeds even if you don't opt in to 4G.
That's because EE is improving the infrastructure across the network, which should improve 3G performance as well as ensuring all that streamed video and photos uploaded to Instagram on 4G phones don't knacker the network in coming years.
EE also claims that 4G coverage is better, even at the edge of a phone mast's signal area. And speeds are promised to be around 8-12Mbps -- check out our speed test to see what sort of speeds we managed with the iPhone 5, Galaxy S3 and the rest of the LTE line-up.
