Sorry, I didn't know much about the unit when I posted that.

No worries.

I have a 3G iPhone and it charged and worked fine (sans the pixelation when you zoom in on the album art). I recently got a 3Gs as a hand me down from my sister and I plugged it in and it charged fine.

Then I wiped it and installed the latest OS and it now will no longer charge and gives me the message "This device is not optimized....".

This does not appear to be a hardware problem at all, rather a firmware issue.

Without the charging I'm debating on keeping my 3G as I do long rides while on calls and need it to be charged. I don't want to upgrade to an iPhone 4 as that means I'm stuck for 2 years.

Any other input to this issue would be appreciated.
