We begin this week's podcast with updates on two topics we discussed last week: the potential purchase of a UK mobile network by BT - and the crowd-funded Jolla Tablet.

After that we talk about the GSMA's reaction to national roaming, the potential death of the landline, a new threat to Google, management changes and advertising for 4G data.

Iain Graham, James Rosewell and Mark Bridge are reunited for their regular weekly look at the latest UK mobile industry headlines.

Today they're talking about smart watches, an Apple iPhone announcement, the new HTC One M8, the closure of Ovivo Mobile, text spam, peer-to-peer messaging, government hacking and mergers.

This panel discussion about new mobile operating systems was recorded at Mobile Monday London on 15th July 2013.

It's chaired by Geoff Blaber of CCS Insight with contributions from the GSMA's Alex Sinclair, David Wood of Delta Wisdom (and formerly of Symbian), Andreas Constantinou from Vision Mobile, Victor Palau of Canonical and Christian Heilmann from Mozilla Corporation.

In this special feature we're looking around the GSMA Connected City at Mobile World Congress 2013.

Mark Bridge and Grant Notman discuss machine-to-machine communications and the Internet of Things, meeting people who've worked with 4G-enabled cars, port logistics, connected houses, m-health and the GSMA's own app development programme.

We're back from Mobile World Congress 2013 with the latest news for the UK mobile phone industry.

Today's conversation covers new handsets, forthcoming operating systems, apps, mobile payments, VoIP, 4G and Facebook's two-tier internet.
