Unofficial Android updates / custom ROMs / misc hackery Other platforms
  • The Nokia N8 was recently blessed with Symbian Anna, but a few camera-related upgrades were left out. No need to fear, as an "experimental" update is now being offered, which adds continuous auto-focus and tweaks the UI to allow for faster access to the camera -- among other improvements, such as a boost to 30fps. Check out the change log here. [via ZOMGitsCJ]
  • Given last week's news about webOS, we were concerned the newly-launched Pre3 would be DOA, with no promise of future updates. HP's proving this isn't the case, however, as the device got a minor update that brought the phone's help center live and fixed a few bugs along the way. [via PreCentral and PhoneArena]
  • Research in Motion released an upgrade to its Tablet OS for the BlackBerry PlayBook. Unfortunately, it's not the 2.0 version we saw leaked screenshots of earlier this week, but it still brings a nice feature to the tablet: differential updates. This means that in future OS refreshes, only the affected sections will be changed. In addition, the new version, dubbed 1.0.7.2942, will improve WiFi connectivity via WEP and enhancements to BlackBerry Bridge. [via RIM]
  • WP7Mod showed a video of the HTC HD2 booting up with Windows Phone Mango's RTM build installed. We've been told that it's almost ready for any daring souls interested in a new challenge for their Windows Mobile device. [via WMPowerUser]
