problem 1:
Once the iPhone is updated with the new operating system OS 3.0, it was loosing the WIFI connection constantly. It wasn't memorizing the connection at all.
Finally I found a solution. I happen to check my router settings (linksys). I see that the iPhone was named as iPhone-2. Somehow linksys thinks that its a new iphone or it gets confused with the new operating system. So all I did was to turn the router off and then turn it on. Problem was solved.
