Ok so I have a iphone 3g and it actually saves all of my recent calls all the way back to the first day I got my phone which was thursday of last week. Now here is the problem.

My aunt just recently upgraded to the iphone 32gB 3gs and it is currently only saving recent calls for the DAY. Not for when she got the phone which was also last thursday. So I am confused. I tried to make the settings exactly but I cant find a recent calls setting.

I tried search, I tried google, and yet to find an answer on how to change it to keep all recent calls cuz an old friend called her and she forgot to save the number and now its gone! Let me know if there is an easy fix.... Thanks
