hi buddies.i have nokia 6600.and when i useto take out my battery n change sim,mobile's time n date was not disturbed from it till TODAY. today when i took battery off n put other sim,it resets the time now! n i hafto set it evytime.can anyone help me ? plz

i thing you update your mobile

I too hv same experience..
Mybe 6600 hv an internal power storage that could be used for certain amount of time.
So if u change ur battery & SIM make sure u do it fast, eg: under 30 sec.
that way the time won't reset.

6600 does not have internal battery to support the time keeping thingy... so if you take out the battery more then 30 sec... it will reset those timer.
