It was very common during early 4.0-4.3 software versions. Especially on iPhone 3GS. Not sure which version you are on but you might consider updating iOS

I leave wi-fi on all the time. I have no issues with wi-fi on my Sprint iPhone 4S. It switches to 3G when I leave my house. What iPhone do you have OP and what ios?
