Dear Albert,
I have just this week upgraded my iPhone 3GS to an iPhone 4S (If my old phone had not been in a swimming pool 3 times and dropped into unresponsiveness I would still be using it, and I don't like to get things as soon as they come out, the second or third batch are always better! What do you mean there's an iPhone 6 on it's way and support for the 4S is going to be dropped... Support? what Support did I need for my 3GS? Anyhoo, I digress...)
To get back to the point, go to Settings / iCloud and switch everything off apart from FindMyiPhone... simple. Forget the cloud, just use it for a back up when you back up to some other place too.
My laptop is still on 10.6.8 (See, I don't upgrade stuff too soon until you are really sure the new stuff is ok) so iCloud isn't even on there in SysPreferences!
I still don't have a tablet of any variety, I just don't see the point
Just because it is there doesn't mean it suits us, I think we all began using apple years ago because we just liked the way they were, stuff worked. It suited us. Now there are a lot more people using Apple stuff, they have to have their needs met too.
Some people need a Cloud...
...Others can make do with just the silver lining!
