Water-resistant smartphones attracted plenty of interest last year at Mobile World Congress... and they were back this year.

UK-based P2i, which already provides a splashproof liquid repellent nano-coating for some Motorola and Alcatel mobile devices, has been showing off its forthcoming ‘Dunkable’ technology. This increases the level of protection by protecting smartphones that are submerged in water.

TCL Communication, the company behind Alcatel One Touch mobile phones, has announced the Android-powered One Touch Idol Ultra.

It’s just 6.45mm deep at its narrowest point yet offers a 4.7-inch HD AMOLED display, an 8 megapixel camera and a 1.2GHz dual-core processor.

James Rosewell and Mark Bridge report for The Fonecast from Mobile World Congress in Barcelona.

As day 2 begins, there’s a review of Monday’s news headlines, a conversation about user experience with Jerome Nadel of Option and a look at water protection for mobile phones from P2i.

The latest large brand to recognise this is Intercontinental Hotels Group, who announced last month that they would be offering free access to 71 million loyalty scheme members’ worldwide. The decision was made in response to a survey in which 43% of guests said they wouldn’t stay in a hotel if it didn’t offer free WiFi.

Let’s start with a slightly belated birthday wish to the hand-held mobile phone, which made its first public appearance on 3rd April 1973. At that point we’d had carphones for a while… but this was the first time anyone had heard the phrase “Sorry, I’ve got to go, the battery’s running out” spoken in public. Or something like that.
