10 must download applications and games from Nokia Ovi Store for Nokia N97, Nokia 5800

Nokia claimed these applications & games will work on Nokia N97, Nokia 5800 and many other popular Nokia phones.

Nokia’s very own centralized application marketplace, dubbed Ovi Store, today officially made its way to the public arena as we expected. It will have to stand up and fight against other notable mobile content stores such as Apple’s App Store, Windows Mobile Marketplace and BlackBerry’s Application Center. Nokia is rolling out the app and content store globally (with credit card support), but currently reserves operator billing for customers in Australia, Singapore, Spain, Italy, Germany, Russia, Ireland and the UK. Additional countries and languages will be added throughout the year, with AT&T planning to make Ovi Store available to its customers in the U.S. later this year.

Nokia claims more than 50 of its mobile devices are compatible with the service as of today, with more slated to roll out over time, and estimates that around 50 million people with Nokia devices will be able to license content and download applications from the Ovi Store right now. The news is now completely out there and people are testing the service like crazy, which means it can be a little slow or downright unresponsive at times.

We’ve browsed the online store extensively and hand-picked 10 applications we think you should download and install first.
