HTC EVO 4G does not have Adobe Flash Player 10.1 support, and it won't get it until the Android 2.2 update is released by Google. This does not mean that you can't view Flash content, you will still be able to view Flash with the included Flash Player lite software but it will be buggy and not as good as Flash Player 10.1.
The HTC EVO 4G will be released on June 4. Unlike the iPhone, Google has taken a positive approach towards cooperating with Adobe and integrating Flash Player in their Android operating system. Right now Flash Player 10.1 is still in beta, and it is expected to be released for Android, Palm Pre, and other devices this year.
Specs of the HTC EVO 4G include a 8.0 mega-pixel camera on the back, and a 1.3 mega-pixel camera on the front for video chat (via Qik), and a 4.3-inch screen. Thanks to the 1 GHz Qualcomm Snapdragon processor, there is a lot of power in the HTC EVO 4G.
