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.

Mobile search is a hot topic again. Earlier this year we reported on mazoom.mobi, an internet search engine designed in the UK for smartphones, and now another mobile-optimised search provider has launched.

Kickvox claims to be the first of its kind, offering “a visual, integrated and categorised search experience that is designed exclusively for mobile devices”.

Mobile Commerce, a UK-based business that provides mobile search services to a number of network operators and other sites, has published an analysis of the words and phrases used when searching on mobile phones.

Can you trust a Chinese company to build a telecoms network?  Apparently not, according to the US House of Representatives. The “Investigative Report on the U.S. National Security Issues Posed by Chinese Telecommunications Companies Huawei and ZTE” wasn’t at all impressed with the two companies, although most of the complaints appeared to be about a lack of cooperation rather than hard evidence. I wonder if any mysterious agents are planning to visit the new Huawei UK HQ before next year’s official opening?
