I'm thinking of buying an iPhone 4 dock for 2 reasons:
The dock connector cable has 2 prongs on the edges to hold the cable in place. This might scratch the iPhone. I've looked at the dock and it doesn't have these prongs, probably to make placing and removing the iPhone easier.
Griffin, the company that made my Reveal Etch Graphite, makes a very interesting accessory, the AirCurve.
The problem is, I looked at the dock today, and it won't fit my iPhone while it's in the case. I can't use it like that. I wonder what other options there are. Do they have extra-long connector docks? Can I use a 3GS dock with a dock adapter? I might buy a dock off eBay, but the quality may be poor and it'll cause more damage to my iPhone.
