This is part 2 of Mobile, Maps & Geolocation - so much more than "Where am I?"

It's a Mobile Monday London panel discussion with Gary Gale, Christopher Osborne, Jeni Tennison, Ian Holt and Harry Wood. Part 1 is available as a separate podcast.

This week's Mobile Monday London event featured a panel discussion about the opportunities for mobile-based geolocation and mapping. The event was supported by UK mapping agency Ordnance Survey.

In this podcast you'll hear the first part of the evening's discussion plus interviews with Nokia's Gary Gale, who chaired the panel, and Ian Holt from Ordnance Survey. Part 2 is available as a separate podcast.

This week's podcast starts with the world's slimmest smartphone (at least for the moment) before introducing a new smartphone company and even more new products from Samsung.

We're also talking about the battle of Instagram vs Vine, the sale of O2 Ireland, mobile retail web usage, the new CEO of BT and a new report about an unexpected health threat to mobile phone users.

Samsung has put a 10x optical zoom lens on a smartphone, Google is acquiring navigation app Waze and the European Commission is getting ready to equip cars with an emergency call system.

We're also talking about a strike threat at O2, the risk of 'showrooming' to high-street retailers, the end of Symbian smartphones and plenty more as well.

We start this week's podcast with Apple's announcement about the new version of its iOS platform - and follow this with a look at the privacy concerns surrounding the US government's PRISM operation.

Next come Samsung's new phones, Ericsson's new contract, a potential end to European roaming charges, some sophisticated mobile malware and plenty of other news stories as well.
