Getting rid of cell standby (battery drainer) is pretty easy, and removing the icons is just as easy, although a bit more involved.
To disable cell standby, thus increasing battery life:
File expert won't let me rename these files. Any ideas on what I'm missing?
- Get a file explorer with root capabilities (i used file expert, free and no ads ^^)
- navigate to /system/app
- rename Phone.apk to Phone.apk.old (disables it, and lets you keep a backup just in case)
