Tone of Your Rings
Knowing you my dear collective, your current smartphone ringtone/notification sound is probably Solid Snake’s CODEC call, the prelude to Final Fantasy, an ocarina tune or some other video game song/sound that only geeks or fellow stealth geeks would recognize (obviously we wouldn’t utilize a tone such as the Emperor’s March from Star Wars and practically announce to the world we’re really dorks).
So, you should probably think of rotating some of those ringtones out. You can easily find new ones here:

Users upload content onto Zedge.net such as ringtones and wallpapers, and usually stay up-to-date with the latest memes, movies or songs. If you have an Android phone, the Zedge.net app is free and works rather nicely.

Also on the Android Market is an app called Ringdroid. If you don’t already have this app, you should download it and use it to shape your mp3’s into ringtones or simply fix a tone you download from Zedge.net. Ringdroid is also a free app.

To stay stealthy, try making your notification tone the piano riff from the beginning of a Left 4 Dead 2 stage.
