I'm looking to increase the days to sync with my exchange server over 1 week.

I've seen "unlimited" option on iphone 3gs version 3 os, but I upgraded to OS 4 before I realized this option was gone.

I'm using a 32GB iphone 3GS OS 4.1. Is there a hack or something to get more messages to sync? Having only 200 messages displayed is not working for me.

Any help would be appreciated! Thanks in advance!!!
