Why would you want your call history to be stored past 30 days anyway? They will probably be over-written with another call anyway. Your concern should rather be whether there is a max number of call histories that can be stored on the phone. My N95 stores up to 20 dialed calls. It would be great if the N900 can go past this number with the ability to not over write call time to the same phone number. With the N95, your call to Stacey at 2:05pm gets deleted if you make another call to the same number at 3:00pm. That is NOT call History.
