Windows Phone detractors, get ready to eat humble pie. The platform has been seeing not just a rapid growth in the number of apps that are being added to the store daily, but also regular updates that include tweaks to make the apps work better. While VoIP app Viber and Facebook has received updates for Windows Phone, cross-platform messaging app Nimbuzz has been released for Windows Phone 8.

Viber’s update is the biggest of the lot, much to the delight of fans of the VoIP app. Viber allows for making not just free calls, it lets you send texts and photos too. Think of it as WhatsApp with calling abilities. The app has received an update that shows a completely redesigned Viber for the Windows Phone platform. The app now allows you to make free calls with HD sound, a vast improvement on the earlier sound quality.

In addition to clear sound while you’re talking over the app, you can now pin conversations to Start via Live Tiles for faster access. You will now also receive lock screen notifications for calls and messages. It is also possible now to connect with up to 40 people in group conversations using Viber.

The app is available for free for devices running windows Phone 8 and can be downloaded from the Windows Phone Store.

Look at all these app updates!

Nimbuzz, on the other hand, has finally released an app for Windows Phone 8 devices. Users who already had Nimbuzz installed on their Windows Phone 7.5 devices can simply update the app. The cross-platform messaging app had revealed last month that it has over 150 million users spread across 200 countries, making it one of the most widely used instant messaging apps in the world.

With the launch of the Windows Phone 8 app, Nimbuzz will be taking full advantage of the platform. It is bringing support for multi-size tiles implementation for Windows Phone 8 devices as well as lock screen notifications. The app has a huge user base in India and the Middle-East. For making messaging convenient to them in a language they are comfortable in, Nimbuzz has added support for Arabic and Hindi in the app update.

Besides Windows Phone, the app also runs on Android, iOS, Java, Symbian,PC and Mac. Nimbuzz recently released a new, redesigned app for BlackBerry 10 too. BlackBerry had in fact selected Nimbuzz as a pre-launch recipient of its new SDK, providing the app makers with advanced tools and resources to build a special version of Nimbuzz that will work across all BlackBerry 10 devices, including an expedited review process from BlackBerry World.

You can download Nimbuzz for your Windows Phone 7.5 and Windows Phone 8 devices from here.

Last but not the least, Facebook for Windows Phone 7.5 and Windows Phone 8 has been bumped to version 4.2 while the app for Windows Phone 7 has been upped to 2.9. While there is no elaborate changelog available, according to the Store description, the app for Windows Phone 8 now has improved performance, support for multiple resolutions, larger tile sizes and more. We’re expecting to see some bug fixes and minor improvements with the update.
