Windows Phone 7 users are required to signin to their smartphones using a Windows Live ID, just like Google’s Android uses a Gmail account. Once signed with a Windows Live ID, users will have access to Zune, Xbox LIVE, as well as Windows Phone Marketplace services.

Even though Windows Phone 7 is still in its infancy, its marketplace already features around 3,000 applications. However, the need for more third-party apps that cannot be found in the marketplace is rising.

Unfortunately, Microsoft doesn’t officially allow users to install third party apps on WM7 devices unless they’ve been approved by the company and posted in the Windows Phone Marketplace.

Until last week, the easiest way to install third party apps was to download them directly from the Windows Phone Marketplace, or, if you don’t care about money, you could pay $99 per year for a developer marketplace registration account. More »

With Windows Phone 7 devices already available for sale in Europe, and coming to US customers on November 8th, Microsoft is working hard to increase the attractiveness of its latest Windows mobile platform.

One critical catalyst of platform adoption is related to the ecosystem of applications available for an OS, and the Redmond company knows this perhaps better than anyone.

In this context, it should come as no surprise that the software giant is offering a range of tools and resources as free download just to get developers to start building apps for Widows Phone 7.

With a developers community already estimated to be 12,000 members strong (and over 1,000 apps already on the Windows Phone 7 Marketplace), Microsoft is offering the Programming Windows Phone 7 ebook for download completely free of charge. More »

It has long been supposed that the GSM mobile phone system was pretty secure and safe from hackers, well, it is, ish… Needless to say that there are ways and means for well-resourced and connected spooks and security agencies, but to date it has been beyond the ability of the average backyard nosey parker, but maybe not for much longer.

Engadget reports that Chris Paget, who has a track record for breaking supposedly secure technology in a helpful way of course, he’s one of the good guys. He has revealed what could be a sizeable flaw in 2G GSM.

At the recent DefCon security conference he was able to trick a number of mobile phone users into making calls through his laptop.

The idea appears to be absurdly simple. Basically he set up his laptop connected to a couple of small antennas as a phoney (pun intended) mobile base station, indistinguishable to phones and most users from the real thing. His kit exploited a feature in the GSM system that tells the phone to log onto the base station with the strongest signal. More »

Mobile phone users that own a Maemo-based handset from Nokia have now yet another reason to rejoice, as the final version of Firefox for their handsets has just emerged on the web. Following a long line of beta and release candidate flavors, now Firefox for Maemo 1.0 is here for them, providing an experience similar in many respects to the one that the desktop iteration of Firefox can deliver.

One of the main feature of the web browser is that it comes around with support for add-ons, something that no other solution offers to users. The add-ons enable any Maemo-based device owner to customize the browser via the over 40 add-ons that are already available for download on Mozilla’s website. Among them, we can count popular solutions like AdBlock Plus, URL Fixer, TwitterBar, language translators, or geo guides. The Add-ons Manager allows for an easy installation of such solutions, and Mozilla recommends for the YouTube Enabler add-on be installed.

The features that Firefox for mobile comes with to Maemo-based phones should be already familiar in a way to those who use the browser on their desktop computers:
