It’s time to ‘ketchup’ with last week’s biggest mobile industry news stories - and where better to start than with HP’s claims of ‘saucy’ behaviour?  It’s launched an investigation into last year’s acquisition of UK company Autonomy, claiming the software company had ‘spiced up’ its valuation. Condiment-based puns aside, it’s a serious matter that could see key players from the deal charged with cooking the books.

Orange Vallée, the part of France Telecom-Orange responsible for innovation and development, has released a free cross-network mobile app that enables users to make free voice calls, send messages and receive voicemail messages.

It’s called Libon and is available as an iOS app in 90 countries including the UK; an Android version is planned for early next year.

EE - previously known as Everything Everywhere - has launched the UK’s first 4G mobile phone service today.

The ‘4GEE’ service is now available in 11 cities across the UK: Bristol, Birmingham, Cardiff, Edinburgh, Glasgow, Leeds, Liverpool, London, Manchester, Sheffield and Southampton.

This week we're talking about the UK's first 4G mobile phone tariffs, Ofcom's consultation about contract pricing and O2's response to its recent network outage.

We're also looking at quarterly results from Google and Nokia, Apple's iPad design, Microsoft's tablet pricing and texting cows.

EE, formerly Everything Everywhere, has announced tariff details for its new 4G mobile phone service in the UK. It’s launching 4G in the UK on Tuesday 30th October in Bristol, Birmingham, Cardiff, Edinburgh, Leeds, Liverpool, London, Manchester, Sheffield, Glasgow and parts of Southampton. Coverage will expand to Belfast, Derby, Hull, Nottingham and Newcastle by Christmas.

The new service will be called 4GEE and promises average speeds of 8-12Mbps.
