Has anyone done that regedit to adjust the # of actual rings before your cell rings?

[efunk33]

There was a regedit going around on all the Windows Mobile phones where you could adjust this with a regeditor. Basically it made it so that when a phone calls you, your phone rings right away, instead of how they come out of the box, where Sprint sets them to have it ring like 5x on the other end before your cell phone rings once.

Just wondering if anyone has done this to their Touch Pro 2 yet, or if they know if it is safe or not.

Thanks
