RadTech 13-860 ProCable Shortz Dock Extender for iPhone, iPod and iPad - Black
It's not the most sturdy thing in the world, but it works. I don't think it's the construction of the extender itself, more of how top-heavy it makes the phone on whatever it's standing.<br /><br />I've got a problem with the dock I use it on not getting a connection very good as the day I got it, but I'll assume it's because I didn't have the phone sitting strong enough.
