I just came across this great site via Techcrunch called “Please fix the iPhone”. It’s basically a list of issues which people are having with the iPhone and allows you to vote on ones you’d like to have fixed.
It’s quite a nice idea and really well executed. What I really liked is the fact that they’ve obviously spent a little time designing this thing (both from a UI and functionality point of view). It’s really quite refreshing to see something like this appear in an era when most simple ideas I see like this end up running on a blog or a wiki platform.
