In this week's podcast we find BlackBerry facing a legal battle, SMS spammers suffering a big fine and EE boosting its 4G data tariffs.

We're also talking about a new iPhone camera accessory from musician will.i.am, rich cross-network communications in Spain, free WiFi in Yorkshire and the year's most-popular mobile search terms.

UK-based Nomad Digital, which specialises in providing WiFi services on buses and trains, has acquired the technology and support operations of Danish business CM Technology.

CMT, which is based in Copenhagen, provides passenger information systems on public transport and in transport hubs.

Virgin Media Business has won its bid to provide a free public WiFi service to Bradford and Leeds city centres.

The service will be operated on behalf of Virgin Media Business by Global Reach Technology and will launch in Leeds’ Briggate and Bradford’s Bridge Street later this month. Millennium Square in Leeds and City Park in Bradford will be added in early 2013.

Nokia has won a patent ruling against Research In Motion that covers the use of WiFi technology in BlackBerry devices.

It means that BlackBerry could potentially block the sale of BlackBerry handsets if the companies don’t agree to a patent licensing agreement. Court action by Nokia is apparently planned in the UK, the USA and Canada.

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.
