Anyone in the UK on Vodafone hoping for some LTE soon will be disappointed, as their CEO has confirmed the carrier won't be switching on 4G until around September. This is in part due to the current iPhone 5 being incompatible with their proposed LTE network. Speaking to The Guardian, CEO Vittorio Colao said:

"We are convinced our own 4G will be better performing. We want to be able to launch it when it's really ready. End of the summer means when there is going to be a good commercial window for launching it."

Currently, the iPhone 5 will only operate LTE on the 1800MHz bands in the UK, while Vodafone acquired 800MHz and 2600MHz in the recent spectrum auctions. Had Vodafone launched soon as they were initially expected to, they would have launched without an LTE iPhone. Not a great marketing play. Stepping back to September plays right into the "good commercial window for launching it," as we're naturally expecting a new iPhone in the latter stages of the year.
