I think these "rumors" show that no one really has any idea what is going on, and people are just thinking up random crap.
Personally, I think the lack of any believable information at this point shows that WWDC is going to be pretty uneventful (by the standards of most) Just more involved promos of 3.0 and 10.6....which I am looking forward to.
Anyway here are the rumors I have heard:
Apple will be releasing a new iPhone with a unibody case carved out of pure platinum (the shavings are thrown away, not recycled). The screen will be carved out of pure diamond. The internal components will be all hand made by virgins. Each unit will be blessed by the dalai lama. The power cord that ships with the phone is not covered in rubber, but by the wing skin of terradactyl that were genetically engineered in a process similar to that in Jurassic Park. Each animal provides for only one cord, or else that would be cheap. It will come with a dock carved out of elephant tusks. The battery will run on power from stem cells. Also, it will not have a name, but will be known only by a symbol because it is too worthy to be called by a name. Each phone will have its own dedicated GPS satellite. It will be free.
If they don't at least come through on those features I am done with apple. I will just go back to my razr.
