Just tried this app out and just wanted to share how awesome it is. Basically, you install it, create an account, and then the app disappears. After that, you can go on their website and it will send a text message to the phone. Give it about a minute and it will show exactly where your phone is. You can then lock the phone, send an alert to it (which by the way sounds like a house alarm haha) and have a little message popup. Best of all, it's free. Don't want to make this sound like an advertisement or anything, but if I ever get my phone stolen, I'm gonna have lots of fun messing with the little thieves
Edit: Wow, now I'm looking at a bunch of similar apps. Lookout, Wavesecure. Which one do you guys like the best? Why?
