Ryan has modded his Mophie Juice Pack Air to include a flash for his new iPhone 3GS.
I got the new iPhone when it came out and I have been taking a lot of pictures and video with it. It's a pretty good camera, but it would be better with a flash. FastMac has an external battery pack with a built in flash, but it looks kind of bulky. I really wanted the Mophie Juice Pack Air to come with a flash, but for some reason they didn't put one in...so I decided to do it myself.
Ryan has been kind enough to provide step by step instructions on how to perform this mod. Hit the link below to read his tutorial.
