Android 2.2 is arguably the most substantial upgrade yet for Google’s mobile operating system. In addition to supporting Flash 10.1 and faster processing speeds, Froyo delivers Wi-Fi hotspot capabilities, new voice commands and “Chrome to Phone” syncing. For a full rundown of what’s different in Froyo, see our FAQ.
As for whether Wednesday is the big day, even if Mashable’s report is spot-on, keep in mind that these updates tend to roll out over a span of a couple weeks. I know of Droid owners who were still waiting for Froyo late last week, and Sprint, which began updating Evo 4G phones on August 3, didn’t finish its rollout until the middle of August.
Sometimes, clever users can find ways to get Froyo without waiting for an over-the-air upgrade, but not until the wireless carrier makes the upgrade official. And for that, we’ll just have to wait and see what August 18 brings.
