I have an iPad2 16GB that serves me well just as it is. I avoid upgrades unless I see an advantage to avoid problems... Something I wanted to do the other day would not work and a message said I needed to upgrade my version for it to work. I have 7.0.6. When I went to upgrade I did not have enough memory - Ithink it said I needed 4.9G to upgrade and I had about 3 G. I removed some photos and music and now have over 5G. Should I upgrade it or not and what would it do to my remaining memory realizing I have a 16G tablet??? Next question - when I look at my ICloud, there is a lot of stuff there. Is there an easy simple way to look at an inventory of what is there and work with it... My free 5G is about used up and I would like to go in and permanently delete some things there but I cannot figure how to do it on my iPad. Using my iPad2 is there a way to access the cloud and look at an inventory of what is there and work on it... If there is, I need a directions for dummies because I cannot figure it out... Thanks.
