I want to downgrade my old iphone to ios 5.0.1 and I want to install some games that are above 1.5 gb until the iphone has only 3 gb of storage free. Why? Because I don't want ios 7 downloaded on my iphone. Now, if I have 3 gb free, will the iphone become slower? And please don't mock me, I also think that this is not true but I am not really sure and I want to see other opinions.
