Revert "Revert "Revert APN refresh time to pre-4.3 value for toro. This increases the speed with which network switching occurs. May be necessary for all Verizon devices""

This reverts commit 147403e64efa54dfbb646446a0544d2525a92ba3.

We're going to try this again to see how it works. We think that the original battery drain issue was either a fluke or caused by some other change at that time.
