Now that Android 2.2 has officially been announced, many users are anxious to get their hands on the latest and greatest version of the mobile OS. The good news for some users is the wait won't be long—Google has already started to roll out the update for Nexus One users. Reportedly, some Nexus One users began receiving the update over the weekend. The installation will likely be spread out over a couple of weeks.
Most users didn't expect the Android 2.2 update to arrive this soon. Last Thursday, Xavier Ducrohet, Android SDK Tech Lead, wrote, "Android 2.2 will be here soon, and some devices will get the update in the coming weeks."
Android 2.2 offers a number of improvements over previous versions. Most notably, 2.2 offers better performance thanks to new technology within Android 2.2's Dalvik virtual machine that runs software two to five times faster. The Android browser is also faster and the OS is better at managing memory for faster task switching. Other improvements include better integration with Microsoft Exchange, additions to the Android Market, and the ability to turn the phone into a portable Wi-Fi hotspot.
