mobile security does use GPS. how it works, is when you want to see your phone's location from the internet. Mobile security sends your phone a encrypted sms that turns on the gps function.
To the OP, sorry to hijack...
well... maybe I'm just using this wrong... I'm just going to say it, ummm... you're wrong. I just went to the web site and "found" my phone. It showed it on a map. It gave the location WITHIN 2550 METERS!!! That's like a MILE AND A HALF!! So, basically useless. Please tell me I'm wrong and using this app and the tracking tool incorrectly.
This app DOES NOT remotely enable GPS. It uses cell tower signals and is not accurate to the point of tracking down a lost phone. There is NO SMS sent (unless I'm not seeing some sort of setting). Even worse, once it locates the phone a nifty message pops up ON THE PHONE saying "found you" so the thief can be fully aware that he's being tracked and make sure that if the GPS was turned off, it would be a swell idea to go ahead and turn it off.
Really great logic there from the developer to go ahead and send an email to an email enabled phone saying it's being tracked, thereby completely eliminating any chance at all of actually tracking it to a thief.
However, the appplication back-up process is good. The contact back up is silly, gmail does that for you. Astro will back up apps, but only on the SD card. Lose the phone and you lose the SD card - so, good idea to use this and Astro.
Virus scan is nice and I like that I can set it to run weekly or daily. I think this app wil be running nonstop in the background and I don't know if it's a battery drainer yet. Be sure to put this app on your ignore list if you're still one the few running a task killer.
