Some of you may want to play with other free/paid keyboards on the Android Market. Well, when I first got my Android smartphone, it took me several hours before I figured out how to change keyboards.
First, download the keyboard you’d like to use from the market.
Once that’s installed, head over to Settings->Keyboard and make sure your new keyboard is checked ON.
After that, you can do a long-press on any “text” such as the browser URL bar and you should be able to change keyboards to your liking.
