Question about Apple iPhone 3G
You can't downgrade to the last version of iOS system, because Apple closes the verification channel once the new system released. So if you want to improve the running speed of your iPhone, see: How to Fix iPhone Running Slow?

Put it back to 4.2.1
It's not the iOS that's slow. It's how much stuff is on the phone.
The more apps, videos, songs, whatever. The slower the phones gonna run.
I have iOS 4.2.1 and mine runs fast, reliable, and does perfectly. But I also leave atleast 1gb free
