I have HTC EVO 4G. I try to install some Apps (say Evernotes). But message says "Your device isn't compatible with this version.

MY EVO 4G had Andriod 2.3.5. Maybe that is the problem. Please teach me how to upgrade my andriod version.

Thanks in advance.

Welcome to AF, AllenTX!
I see Mike has pointed you in the right direction to learn about the possibilities with rooting your Evo. If there is anything else you need assistance with, please ask.:)
