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 ebc38d0965f8e24ac8669e99a9534381aa044c6e. This was meant to fix data connection issues but had no major effect. It instead made battery life worse for toro users in some network situations.
