Hey guys, please forgive my newbish questions. I rooted my Evo 4g when I got it 2 years ago and I have not played around with it since. It has Android 2.2 on it and hboot 2.10. I have seen there are much newer Android version out now that help with many of the problems I have with this phone. I started reading the rooting guide for dummies and it just made me even more confused with radios (have no idea what that is!), wimax etc etc. I remember when I did this it wasn't so complicated it was pretty simple. so.. How do I know which android version to upgarde to for this phone that is stable and I don't lose any ability like 4G or something else? Is there a simple way to do this since my phone is alrady rooted and basically all I want is the newest version of android? Thank you in advance for answering my stupid newbish questions.
