I've recently got an iphone and love it, but am wondering why the lock screen is necessary? I always thought it was so your iphone isn't accidently turned on when its in your pocket or something. But, I've found once the screen turns off, you can't turn it back on without pressing the home button or the on/off button. No amount of accidental touches to the screen in your pocket is going to turn it on. Also, the chances of pressing the home button or on/off button accidently are quite slim, since one is depressed and the other takes a fair amount of force to press I've found. It seems like an unnecessary feature, unless I'm missing something. It would be much more user friendly to just have the screen turn off and lock like it normally does, but when you press the home button or on/off switch, it would take you directly to the main iphone screen(no lock screen at all). Anyone else agree?
