Regain iPhone 3GS WiFi Back by Turning off Bluetooth???

I’ve had WiFi signal issues with both my iPod touch (1st generation) and iPhone 3G since upgrading both devices to iPhone OS 3.0. Both devices have problems getting WiFi signals in weak signal areas where they used to be able to grab onto it. Some 3GS owners have reported even more severe problems like not being able to use WiFi at all. If you are among those unfortunately people, this item from TUAW may help you…
