I've been reading this forum for quite some time now, but somehow I never had to post anything.
I modified my iPhone 3GS because I didn't like the feel of the plastic back. It took me a couple of month to do it, and as I never dismantled an iPhone, this forum was a good help to learn something about the iPhone's hardware.
Basically I designed a new back cover for the 3GS. I had the original cover measured digitally, and I then started to draw the new cover in CAD. It's made out of a special titanium alloy that is RF transparent. I had tried aluminum but that was a complete disaster.
All in all I'm very happy with it, although there are some little things I need to fix before everything fits perfectly.
Here are some pictures of the latest prototype, i hope you like it!
Cheers, Martin.

UPDATE2: Since so many people asked, I would like to clarify that this project is a modification of my personal phone, for private use, and that it isn't for sale and won't be sold. Unfortunately it is not possible to buy this mod or the CAD drawings. However, thank you very much for your terrific support, I appreciate it very much!
