Apparently, Steve Jobs is responding to e-mail.  On a regular basis.  In addition to responses regarding the iPhone Developer Agreement, he responded to a fan's question about OS 4 compatibility on the original iPhone with a short "sorry, no."

Though it appears to be an official e-mail from Jobs, the company hasn't commented just yet, so anything could change between now and then.  On one hand, I understand, as the phone is three years old.  On the other hand, it could be done (perhaps in paid form, like the iPod touch updates).  For those that still own and use your ($400) 2G iPhone on a regular basis, how do you feel?
