According to a very scientific poll at everythingicafe, 41% of people put their iPhone in their right front pocket and 34% in their left front pocket. (http://www.everythingicafe.com/forum/threads/which-pocket-do-you-put-your-iphone-in.57830/).
I'm a right-front-pocket type but I hate it when my iPhone slips down to the bottom of my pocket and sits horizontally across my leg and it's worse (all bunched up) when I sit down.
I know, it's not the end of the world, but I decided to do something about it.
Step 1: Where the IPhone Wants to Go
Here's the shape of the front pocket and it is no surprise that the iPhone wants to slide down to the bottom.
Step 2: Where I Want the IPhone to Go
I'd like the iPhone to sit next to the side seam and you can see the pencil lines I've drawn in my plan to split the bottom of the pocket and square off the bottom of the "iPhone" side. I want to make the divider just over halfway up the iPhone (to the bottom of the Apple logo). That should be enough to keep it vertical and still make it easy to get the phone in and out of the pocket.
Step 3: All Sewn Up
That took about 2 minutes and you can see I went a bit bigger than my pencil lines to be safe and in the next photo you can see how the divider looks inside the pocket.
Step 4: That Works for Me...
So when standing up, the iPhone is hard to see and it is much more comfortable when sitting down. Also if your sewing machine is set up, it will probably take you less time to do this than it took to load and read this instructable.

Step 5: Variations on a Pocket Theme
I started through my wardrobe and found that pocket shapes vary quite a bit. Here are some pics of various pocket shapes and where I put in the dividers.
I also discovered a secret iPhone pocket in a pair of Carhartt dungarees, but that's another Instructable...
If you put photos of your iPhone pockets or before/after shots in the comments below, I'll post them here.
