Microsoft has found the root cause behind the SMS vulnerability in its Windows Phone operating system. The bug was reported earlier this month by Khaled Salameh, who found that the platform could be exploited via a malicious SMS message that forces a Windows Phone device to reboot and then disables its messaging hub.

Although it is good that Microsoft has found a fix for the bug in Windows Phone devices, the exploit may also affect its other applications. So far it is known to work not only through SMS messages but also through Facebook chat or Windows Live Messenger.

A newly leaked Windows Phone roadmap has surfaced that gives a rough time frame for the launch for the coming versions of the OS. According to the roadmap the expected Tango flavor of WinPo for lower end devices will be launching in Q2 2012. The roadmap is supposedly up to date as of October 2011. That is a few months back now and things change quickly in the tech world.

Take these dates with a grain of salt. The roadmap also shows that Windows Phone Apollo will be launching in Q4 of 2012. Apollo is the update for the OS that is supposed to make the devices running Windows Phone more suitable for business users. Apollo is also said to be the code name for Windows Phone 8.

NAVIGON updated its Windows Phone 7 app, allowing users to download maps by state, while also including other features to the mix. Here is whats new:

• Active Lane Assistant – reflects the current lane configuration and enables drivers to see ahead with orange line indicating the way the driver should follow.

• Live Weather – current weather conditions along the route and at the destination in real-time.

• Optimized positioning

Microsoft has just added some improvements to its SkyDrive service, making it play nice with 3rd party apps. SkyDrive, which is one of the key selling points of Windows Phone platform, now grants non-Microsoft apps full access to SkyDrive, allowing them to upload and share all kinds of files.

This should allow the development of much richer WP apps that do not take a lot of space. And since the Microsoft platform refuses to allow user replacement of the microSD cards, storage is quite valuable there.
