Welcome to Android Central! You booted into Download (Odin) Mode, which is used to copy over a firmware file from your computer (if connected via USB). If you're not connected and not transferring a file, you can shut down (pull the battery), then power up normally using the Power button. If you want to boot into Recovery, follow the steps here and wipe the cache partition while you're at it: http://support.t-mobile.com/docs/DOC-5744
