The United States International Trade Commission has ruled in favour of a Samsung complaint about one of its 3G patents, banning older Apple iPhones (anything before the iPhone 4S) and older iPads (first and second-generation models) from being imported into the USA and sold there.

Newer devices aren’t affected.

Not too long ago, iPhone enthusiasts rallied the White House with an online petition to legalize out-of-contract iPhone unlocking. The Obama administration cast its support that generated only a lukewarm response from the industry. Not surprising: the top three U.S. wireless carriers - Verizon, AT&T and Sprint - have relied on contracts to sell cell phones for over a decade. With Apple's introduction of iPhone - the most expensive smartphone in history - the carriers could then generate lucrative profit margins on each and every phone sold under contract. And to make sure the customers wouldn't 'jump ship', the carriers locked in all subsidized iPhones.

Apple’s results for the second quarter of its current financial year - the three months until 30th March 2013 - show quarterly revenue of $43.6 billion (£28.6 billion; up 11% year-on-year) and quarterly net profit of $9.5 billion (down 18%).

It’s the first drop in quarterly profit for several years.

We start this week's podcast with financial results from EE - along with new phones from LG and HTC.

There's also a merger between mobile browser companies, mobile security from Vodafone, free WiFi from Barclays bank, a preview of Ubuntu for smartphones... and much more.

There are many mobile boundaries being blurred in this week's podcast.

Topics include Truphone's combined WiFi and mobile service, Skype's move to direct mobile billing, the rise of 4G and an Android-controlled satellite.
