Okay, once again...just got my iphone a couple days ago. I was very excited to go to church today and not have to carry my big bulky Bible, was going to use my iphone instead...SO I thought for SURE I put my phone on vibrate by turning vibrate on in the settings! Sure enough, I get a text and guess what...it's as loud as the Pastor. UGH! HOW do I set my phone to vibrate to make this not happen again?
