Rooting the Incredible technically is very easy now with any of the methods you can lookup on google. HOWEVER What I have found out and cannot seem to figure out why its not mentioned, is that some hboot versions are incompatible with doing a root. When I finally figured this out and upgraded the hboot to a different version, root was achieved in a matter of 2 minutes taking my time with screen shots and jumping for joy.
Using AnyCut.apk will help you get into the APN settings and even the Proxy Settings to get WAP working, even tho the Cricket APN isn't visible, its there after you set it up properly. EPST is the same from all other phones I've done, except these droid phones have a couple additional settings but they are clear enough to figure out on the first try.
MMS is the same as the Hero, just follow the instructions and you got MMS.
My goal now is to figure out how to get complete functionality with WAP so apps use it. Currently only web browsing is possible from what I can tell. SenseUI's weather only works on wifi, apps only works on wifi, any app that uses the internet will only work on wifi.
If someone has a workaround for this, please mention.
Anyway, I have a 90% Fully Flashed HTC Incredible and I love it now! However I say go with a Evo haha, Sprint isn't anal with their phones like verizon is.
