Hi guys, Forgive the newbie questions, but I'm a recent convert to Mac (Mac air 13") and am now thinking of switching from android when my verizon contract is up in two weeks. Looking at the iphone 5s. Couple of questions though: 1) Can you change the strength of the vibration option? Sometimes I'd like it to be weak, other times strong. My current phone -- LG Lucid -- has one strength only, and I consider that an annoying drawback. (Particularly since my phones 10 years could.) 2) Any other cool vibration options? A favorite I had on an old Startac was a vibrate 4 times, then ring two times. 3) Is it stupid to buy an iphone 5 now, when there are rumors of a larger 4.7 model coming in the fall? (I would prefer a phone with a slightly wider width than the current iphones.) Anything else I should know or think about?
