It looks like EVO 4G users will soon have one more thing to smile about, as Sprint has just announced that an Android 2.2 (aka Froyo) upgrade will indeed be coming to the "superphone."
With the Android 2.2 upgrade, customers can expect improvements to include the following benefits: updates to user interface, improved EAS Support, improved browser performance, including Flash 10x Support, voice dialing over Bluetooth and application storage on external memory.
No word on a timeframe yet, but you'll know as soon as we do -- promise.

Update: According to this tweet from the carrier: "HTC EVO will be updated to Android 2.2; Samsung Moment & HTC Hero will not. Future devices launching w/ 2.1 will be also be updated to 2.2."
