no no no - the call log history as a separate entity is still there! do not distress
go the __ folder and you will see a phone in ghost (=hidden). unhide it and put it on your home screen!
it's a great way to JUST see a call log, no other garbage. and even if you were to go to the messages icon and delete stuff, the call log will still store everything. it's great.
hope that helps!
