days ago applehound.com published a list of 68 iPhone bugs. The site claims "all (bugs) should be reproducible by every iPhone owner".
The list contains few truly serious bugs, and the guys claim that OS X and the applications are very stable.
However, thanks to a couple of hundred comments, you can find a few more. More and more people are writing, hoping that these small but annoying issues will be resolved with some new software.
If you haven't had enough iPhone news for a lifetime, you can see the list here
