iPhone 4S vs Droid Bionic, Samsung Galaxy S II, and the HTC Titan

I am excited about all the Iphone 5 rumors but I NEED to know... are they true? My Iphone 3GS has had it. I have dropped it so many time so many times have stopped working. I was super excited when I heard about the Iphone 5 launch, only to go to the website  and discovered there is not Iphone 5 (yet) the launch for the the Iphone 4S. I am disappointed and trying to make a decision on if I should just wait for the 5 or go ahead and purchase the 4S. I need a new phone ASAP so the decision may be made for me. SMH
