iPhone 4 shows 3G icon instead of wifi icon when a wifi is available

If iPhone 4 shows 3G icon, it means you are using 3G network and you are using your data plan. If you don't believe it, go to Setting and turn off both 3G and cellular network. You'll find you cannot connect to internet any more.
To solve this problem, you'd better get your iphone's MAC and reserve an IP address for it in your router. You may be able to find out the phone's MAC from your router.
