Just an FYI, the x-terminal has a virtual tab key which can be used for auto completion. So there is no need to rename long files. The terminal is smart enough to recognized the file name in the directory your telling it to execute the command. I use this all the time, so much faster.

Just start typing the name of the file then after the first few letters press tab. Works for almost everything you do in xterm.

Have fun with the phone. It's awesome!
