Improving Tower Polling / Ring Response Times

NOTE: This is not an original hack. I found this in a forum.

The ring response time of the 6700 is fairly poor due mostly to the tower polling time. Fortunately, the handset includes a custom PST. To improve the tower polling, do the following:

Dial ##778 (PST) on your handset and press Talk
Enter the security code (000000)
Choose "Modem Settings" off of the PST menu
Change "Slot Cycle Index" to 0, or 1. This value is 1.28 seconds * 2^N, where N is the index. A value of 0 will give you the fastest tower polling, but most people stick with 1 to avoid excessive battery usage and flooding the network.
Click OK and you will be prompted to soft-reset your handset.
