No prizes for guessing which two mobile tech stories grabbed most of the headlines last week. Tuesday morning saw Nokia’s much-rumoured tablet and phablet launches, with a Windows RT device and two 6-inch smartphones joining the company’s product portfolio.

This was followed on Tuesday evening with Apple’s big news, which centred on its Mac computers and its iPad tablets. There’s a new iPad Air, which runs on the Apple A7 chip and is thinner than ever – and there’s a version of the iPad Mini with a ‘retina’ display.

However, music retailer HMV wasn’t feeling any warmth towards Apple, having discovered the HMV iOS app had been suspended from the Apple App Store. Apparently it was the non-iTunes shopping wot dun it.

Talking of complaints, there’s something of a major spat going on between security company NQ Mobile and by investment research business Muddy Waters. Muddy Waters described NQ as “a massive fraud”, leading to NQ calling the allegations “false and inaccurate”. Somehow I don’t think that’s the last we’ll hear of this.

Being trapped in a contract when the prices go up is one complaint UK regulator Ofcom is determined to end. It’s clarified the rules allowing customers to withdraw from a fixed-term contract if there is any change likely to be of ‘material detriment’, telling phone and broadband service providers any increase to the subscription cost is likely to be regarded as such a change.

It’s also published a report on telecoms infrastructure that shows public WiFi use growing at a faster rate than mobile data – and has revealed details of “significant gaps” in mobile coverage on UK roads.

Finally, the Metropolitan Police has pointed out that Apple devices aren’t just popular with customers. They’re also a target for criminals; around 10,000 mobile phones are stolen in London every month and around half of these thefts are iPhones. Let’s be careful out there.
