Re: My list
Err no, why comment if you don't know this to be true? The file explorer is there on iPhone as well. As you would expect, it functions more like the Finder function of OSX and just shows you files, not the inner workings, but what did you realistically expect?
I do miss the back button on Android, but not enough to get an Android phone, somehow.
Never used Contact Shortcuts, do can't speak on their usefulness. Sudoku Apps, I somehow think amongst the 2 million apps there must be one. I think if you uninstalled all the apps from the iPhone and used it as stock, the battery life would be huge :)
