Everyone has been waiting to see just what Vodafone will offer with its 4G service and now we know. Sadly, it doesn't look like it massively undercuts the opposition.The date for your diary is 29 August, with Vodafone offering the service in London from that date. That's right, just London, with speeds in the capital likely to be six times the current 3G speed. Once London is up and running, the next places to feel the Vodafone love will be Birmingham, Bradford, Coventry, Edinburgh, Glasgow, Leeds, Leicester, Liverpool, Manchester, Newcastle, Nottingham and Sheffield before the end of the year.You'll need to sign up to Vodafone Red 4G-ready to get the service and of course, have a 4G device, which doesn't include the iPhone 5. But hopefully the upcoming iPhone 5S will address that problem.As for pricing, the entry price is £26 per month on a 12-month SIM-only plan (if you already have a compatible phone). Other deals vary depending on your needs. A 24-month deal including a handset starts at £34 monthly or £52 if you want 12 months. 2GB of data is the limit for the cheaper deals, but you can jump up to 4GB and 8GB deals if you want to pay more. The entry level freebie phone looks like the Samsung Galaxy S4 Mini, with the Galaxy S4 offered for 'free' with the pricier packages.Tablet and dongle deals are also on offer. In terms of the former, the Samsung Galaxy Tab 3 (8-inch) is available for £31 a month with 4GB of data or for £36 a month with 10GB, while the Sony Xperia Tablet Z is available for £37 a month with 4GB of data or for £42 per month with 10GB of data. For dongles, you are looking at £20 monthly for 4GB of data, with a £29 upfront cost.Finally, Vodafone has another sweetener for potential customers. New 4G customers will either get access to Spotify's 20 million song collection or 150 hours of Premier League football and unlimited data for the first three months. Not bad as add-ons.All details on all deals are available from the Vodafone website. If you haven't got coverage for your area, it will eventually find you. Vodafone says it will bring indoor 4G coverage to 98 per cent of the UK population by 2015.
