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
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.
