I've recently run across a number of great resources while researching my Sprint EVO 4G phone, which runs the Android operating system and is quite tweakable.

One of the top resources I've found is called Good and EVO, a blog that answers in patient detail lots and lots of great questions. Anyone who has the device and doesn't know where to start but wants to learn about the phone and how to make it really work should read through all the articles on the site. It's very well-written and contains a wealth of information and links. Check it out at http://www.goodandevo.net/.

**Another excellent - and more technical - resource is the xda-developers Android Development forum for the EVO 4G phone. **Uber-geeks will rejoice in all the slang and tech jargon being slung around the walls of these rooms. Of particular interest for people getting started hacking on the EVO is "rooting" the device and installing customer ROMs (images of the operating system packages). Check out the EVO Helpful/Popular Threads topic for links to the basics, and check out the broader forum for lots and lots more. The forum can be found at http://forum.xda-developers.com/forumdisplay.php?f=653.

Other good resources to list?
