I know this sounds ridiculous and I should know the answer to this I should feel by now. Lately my 3GS has been acting a little weird whenever I closer out of an app switch apps it seeks that the app squares and the dock are enlarged for a quick second then go back to normal. It started to irritate me so I did a restore. My phone now feels a lot quicker and doesn't have the problems it did before. So my question is, is it actually a good thing to do a full restore now and then? I would expect apple to have that in words somewhere just to give the customers a heads up.
