We're talking about Nortel patents, Google Plus, roaming charges and health concerns in this week's mobile industry podcast... but that's not all. We also discuss mobile payments, security, gambling, apps and the Pope's first Tweet.

The European Parliament says member states should publicise the 112 emergency number in doctors' surgeries, pharmacies, schools, universities, airports and railway stations.

A survey published earlier this year found that only 26% of EU citizens could spontaneously identify 112 as the number to call in an emergency abroad.

Last month Juniper Research said the number of mobile phone users making payments for digital goods was expected to reach 2.5 billion worldwide by 2015, a 40% increase from this year's forecast of 1.8 billion.

It's now published a new study that looks at all mobile money transactions. The company says the total value of mobile payments for digital and physical goods, money transfers and NFC transactions will reach $670 billion by 2015.

Recently Pizza Express introduced a new iPhone application that lets customers book a restaurant table and pay their bill. The app was developed by 2ergo, a UK company based in Manchester.

Last week I spoke to Colin McCaffery, Product and Technology Director at 2ergo, to find out how difficult it was to get the app and the restaurant's own technology working together.

Anonymous opinions about technology are all over the web... and they're not always pleasant. PC versus Mac. Apple versus Android. WiMAX vs LTE. Even a relatively light-hearted rant can be misinterpreted. Still, if some unknown voice is trying to irritate you, you just ignore them - right?

Wrong. Not if you're Research In Motion.
