We've been following the Homebrew Device Manager by Schapman for some time now and it has now been released as a Beta. The Device Manager features include:

  • Applications management: view, install/uninstall homebrew applications
  • File management: explore device, exchange files with your phone
  • Sync files, folders and favorites with phone
  • Send to Windows Phone (to send files, apps, ringtones, web links in one click)
  • Detailed device information (CPU, ROM, RAM, storage, network, battery, OS,...)
  • Add and manage custom ringtones

Additionally, TouchXperience for Windows Phone 7 has been released as a Beta. The navigation app was well received back in the Windows Mobile days and it doesn't miss a beat on Windows Phone 7. Key features of TouchXperience include:

  • Create custom menus
  • Add folders, apps, contacts, websites, maps, documents, and many other widgets
  • Organize applications & games
  • File explorer
  • Multitasking support
  • Panorama background customization
  • Contact manager
  • Communication manager
  • Profile manager
  • and more

Keep in mind you'll need a registered or unlocked Windows Phone 7 device to use either. You can find all the details on Windows Phone 7 Device Manager and TouchXperience here at the TouchXperience website and after the break, you can catch a video demo of TouchXperience.

Thanks, @KingpinEX, for the  heads up
