• SD card installations: Yep, you'll finally be able to install apps Google Android Apps: SD Cardon your SD card, smashing the space limitations of Android versions past. You'll be able to select where you want each app to be installed -- SD card or internal storage -- and even toggle it back and forth with a couple of clicks later.
• Auto-update and update-all functionality: Froyo introduces the option to have your apps automatically update themselves when new versions roll in; you just configure the permissions to your likings and Android does the rest. If you decide to stick with manual updates, Android 2.2 will let you update multiple apps at the same time with a new "Update All" button inside the Android Market.
• App backup: A new option within the Android settings menu lets you back up and restore your apps' data. You could use this to recover lost information or even just move data and settings from one phone to another.
• Cloud-to-device messaging: It's as cool as it sounds. Android 2.2's new cloud-to-device messaging capability means developers can build in Web-based functions that will communicate directly with your phone. So, for example, you could click on a button in a Google Map on your PC and have it automatically open the same map -- complete with driving directions -- on your phone. Not too shabby.
