Nice one, that exactly what made me want to get into photography, holding my girlfriends 3meg Nokia N73 phone up the eyepiece. I was really impressed with the result. I use that picture as my wallpaper on my itouch. It's amazing what you can do with house hold equipment.
Be careful though, now that you have the bug, it starts to get very very expensive lol.
excellent first results, 
keep em coming.
