I bought a 3G iPhone last Monday. I absolutely loved it. Two days later I decided to upgrade to the 3Gs and just picked it up today.
These phones are AMAZING. Period.
I own Apple and RIMM (Blackberry) stock so I figured I would go into the store with an open mind to the two companies. IMO, the iPhone blew the Blackberries out of the water.
My dad picked up a 3G iPhone as well and he is not the most tech savvy guy. He adores his iPhone and can't even remember how he operated his business without it...
