last week i had my ipod touch stolen and theres no way anybody is going to get my storm, but when i downloaded the gps tracker app it says unable to access gps. i created the account and my number i put in is correct.
Check out SmrtGuard... It's still in beta and has some pretty sweet features... One of which is GPS tracker.... And if someone does steal your phone you can log on to the web site and send a command to your phone to wipe it totally clean of all your personal stuff!
Fair warning though, depending on your OS, could leave your phone running slow...
