Entered Contact, Now Lost.... Notepad?

Well, I drove realy far out to meet this girl I saw a while ago. I got her number and entered it in, and then I entered her name, and I guess I closed the phone too early (I have a Razr by the way). So I get home and look it up and there is no such entry for her name. I checked in the notepad and a number that sounded familiar was in there but I wasn't sure (I hadn't dialed any numbers after I dailed hers, I didn't even use my phone in that time). I went ahead and added that number as her contact, and sent her a message, i have yet to get one back it being ten minutes since I did. I just wanted to make sure that that would be her number in the notepad...

Well, turns out it was her number, she texted me back a few hours later. I think that feature of the notepad is awesome, hopefully I won't have to use it again though!
