iPod touch upgrade to ios4 on ipod touch issues

[penym]

Hi,
Yesterday I tried to install ios4 on my 2nd gen ipod touch. The upgrade went ok half way and later due to some error it keeps on rebooting continuously.
In itunes I get following error.

iTunes could not connect to this iPhone because an unknown error occured (0xE8000065).

The device I am using is not even an iPhone..!
I am currently not able to boot my ipod. I tried reset several times, tried using different pc.. but no use.
Any help appreciated.
thanks

Mine updated fine, but now my Touch (2nd gen) runs slower. Painfully slower. I've got a first gen I haven't updated and side-by-side the difference is obvious. The iOS4 Touch is slower. The UI is slower. Apps run slower. Graphics have lost their fluid dynamic.

Me too. Is there any way to go back to the earlier OS?
