So we're finally at a place where we can start talking about iPhone accessories. On the iPhone debut day, we picked up just one accessory: Power Support's Crystal Film Set. This accessory will protect the iPhone screen from dirt, dust and most scratches. The best part of this film is that it uses static cling for adhesion and won't leave a residue when removed. Supposedly it's repositionable as well, but we haven't tried it yet.
After putting the film on our iPhone, no one noticed it was even on. It's pretty invisible, and fits perfectly. It can get a little tricky to put on so take your time.
A while later we tried our iPod audio out dock connector that we use in the car on the iPhone and found that it doesn't work at all. We're wondering if the audio out of the iPhone is hooked up differently than a normal iPod. We then found the 1/8" audio jack didn't fit in the iPhone's recessed plug connector. A trip to the Apple store led us to the Belkin audio adapter for the iPhone.
While the adapter is a bit large, we found that it was the right size and fit the iPhone's tiny jack like a glove. It looks ugly, but it works to get audio back into our car with the iPhone. Hopefully some manufacturer will come out with a tiny dock that allows audio out from the iPhone.

I too am looking for some Accessories for the iPhone as it will soon be available in UK too. I found a nice list of iphone accessories on a blog, but i still need some more. Do you know any other iphone accessories tops or list? 10x. I'm looking for your answer.
