2. Many apps aren't showing up for me in the Market! WHAT DO I DO????
While this still won't show ALL apps, doing the following will certainly help you to find MORE apps in the Market:
Open Root Explorer, navigate to system/, mount as r-w, and open build.prop in a text editor. Find the line that starts with ro.build.fingerprint= and change it to the following:
ro.build.fingerprint=verizon/voles/sholes/sholes:2.1-update1/ESE81/29593:user/release-keys
Now from your homescreen, hit Menu>settings>Applications>Manage Applications>All, and find Market. Select clear cache, and then force stop. Then, still under All, find Google Services Framework, and hit wipe data, and then force stop. Reboot, and many more apps should show up!
