Guys, I'm confused. Saw this app appear after ICS legal upgrade to ICS on Moto Droid Razr: 1. Turn off radio. What does this mean? GPS, BT??? I don't know and can't find documentation 2. Turn off IMS Registration required. What is this? 3. Turn on SMS over IMS Help! 4. Turn off LTE ram dump? What do I need to do? Should I do anything and if so for what reason? 5. Toggle DNS???? Pls help, any info is very appreciated.
