When Android 2.2 becomes available for the HTC EVO 4G in the second half of this year, I don't think anyone will think twice about updating. But just in case you have some reservations or aren't sure of what you'd be getting, here's a list of the new version's main improvements.

  • Android 2.2 runs between two and five times faster than 2.1
  • Faster, more powerful browser with Adobe Flash, Adobe Air, and improved JavaScript performance
  • Faster app switching and smoother performance
  • Bluetooth voice dialing, dock/car kit support, and contact sharing with other phones
  • Exchange support with improved security, remote wipe, auto-discovery, global address lists look-up, lock screen timeout, and calendar sync
  • Alphanumeric password lock
  • Permanent home screen "dock" with shortcuts to app launcher, phone, and browser.
  • Camera portrait mode, zoom controls, easier access to settings, thumbnails, and exposure data
  • Camcorder LED flash and easy way to optimize for YouTube and MMS
  • Tethering and portable hotspot support (the EVO already has hotspot functionality for $30/month)
  • Multiple keyboard languages
  • App improvements
