Quick, name the application store that has 140,000 apps, has 23,000 content partners and has facilitated over 100 million downloads with an average paid value of over $20? Give up? It’s Handago, or for you old Palm people, PalmCentral. Launched as PalmCentral ten years ago, Handago now supports 8 different operating systems. The company is celebrating their 10 year anniversary.

Originally, PalmCentral supported PDA owners in their quest to download new applications. As times changed and smartphones took over, the name was changed to Handago and they currently support Palm OS, Windows Mobile and Pocket PC, Blackberry, Symbian, UIQ and most recently, Android.

Getting a smartphone? Want a hand getting applications we’ve all been talking about? Head on over to Best Buy where they and Handago have worked together to put Handago’s store on the handset and assist with getting apps on your device in the store. Best Buy says moving an app store into brick and mortar space.

No longer content to just offer Palm apps, Handago now offers apps for Windows Mobile, Blackberry, and Symbian S60 smartphones. They offer over 140,000 apps.
