I JUST started Google Latitude last night. My boyfriend is the one who sent me the invite. I added it through my phone and went to bed. I did not leave my house the entire night. About 4 hours after I had launched it, the GPS mapping showed that I left my house, drove down the street for a bit and then returned home 2 hours later. This is impossible as I was home in bed with my phone next to me. Is there a way someone could have hacked the account or the phone? Please help! This is causing an issue in my relationship and I don't even know how the dumb thing works and if someone could hack it.
