CallHistoryMax issue

[rex]

Has anyone found out how to truly make the call history unlimited. yes I do know about the registry tweak with CallHistoryMax set to 65535. but even that does not let more than 300 calls in the call history. i go through 300 calls in less than a week.I have searched far and wide at every ppc forum but i dont see any comments beyond the 300 call limit.
can any of the programming gurus/geeks (Helmi?? Colone???) pleez findout/ let me know if there is any real way of making the call history unlimited. having been with treo, this is a luxury hard to give up.

I have now PIMback that backs up twice a week. still seems too cumbersome to have to restore call history to look up a number.

Pleeez help if anyone knows anything.

thanks
Rex.
