I'm on ICS 4.0.4, and am using the latest GO Launcher. My phone is slow. Not sure what did it, if it's the ICS or the GO Launcher. But I do want to keep my same functionality. How can I speed up my phone...er, clear it out? Is there some MSCONFIG-like utility I can use? Can I clear junk out? What would be the best way to back up texts, data and contacts?
