Since you no longer get any sort of owner's operating manual with electronic devices anymore it's difficult to find answers for stuff like this. Sometimes I find a little info online but it usually isn't directly related to my situation and is seldom very specific, so it doesn't help much.
When I started looking for a replacement phone I thought about getting a iPhone this time (I've always had Android phones). But three things stopped me; for the most part I still just use the phone as a phone so all the extra features of a iPhone would be wasted, I'm comfortable with how Androids work (know nothing about iPhones), and the iPhones were way too expensive for me (the new Android was about 20% the cost of a iPhone). But I admit they are impressive.
