We'll let that sink in for a minute.
So here's the deal: You're getting an update from Android 2.1 (Eclair) to Androird 2.2.1 (Froyo). Along with that, you'll be able to install applications to the phone's microSD card, you get better Bluetooth support and voice dialing, Adobe Flash Player 10.1, GPS improvements, new security features and data tethering over 3G and 4G.
The update -- EB13 for those of you who care about version numbers -- will start pushing out to phones in batches at 9 p.m. (Pacific time, apparently
Eastern time we presume) tonight. If you don't get it at first, don't worry, it'll be rolling out in waves over the next four days. (And we'll have manual installation instructions soon enough.) Everyone should have the update by Feb. 25, Sprint says.
So that's it, congrats, thanks for waiting and being (cough) patient. Enjoy your update. [Sprint]
