Is it worth getting a iPhone if I have an iPad?

Ok well I have an iPad 2 with just Wi-Fi and I love it to bits. It stays at home all the time except if I go on holidays (which is rarely). I need a new phone and I'm really interested in a iPhone 4s but is it worth getting that if I have an iPad? Will I continue to use my iPad? Do any of you guys have both?

My iPhone 4S turns off for no reason?

Sometimes I will be able to use it for over a half hour when it's at 1% battery, but other times it will shut off when there's battery life remaining, e.g., 8% or 12%. And just now it turned off at 27%! This doesn't seem normal to me. Does this happen to anyone else? What could the problem be?

IPhone screen popped put but still working?

I dropped my iphone 4s and the screen cracked and little bits started to chip of around the home button and pretty much the whole area above the screen but now its completely popping out on the left side, but its still works (except for sound camera and vibration but anyway).Is it dangerous to use it like this (i'm using it now)? I haven't had it for a year yet and I'm with Telstra, will they fix it under warranty?
