Tele-phone number got removed from keypad

[Goooner]

Hey guys this is my first post on CB. I purchased a bold 9900 a few weeks ago and so far am really enjoying it. However I have one issue which really pissed me off.
After getting to know this really hot girl for the duration of my train journey. I ended up getting her number which I typed into the keypad, after getting off the train I looked back at my phone (which had locked the screen). I noticed that the number was removed I know I should of saved it there and then, but I was carrying my bag of the train, queing etc and am used to my old iphone where you simply press the keypad and the number is untouched. So my question to you guys is.... Is there any way to get the last number typed into the keyback back on the screen ??

Thanks in advance

You would have a point if, I actually touched my phone! The screen auto locked and wiped it. Nice try smart arse go back to sniffing your nans knickers. Creep
