Is there an app out there that will keep my Iphone's Wifi alive while it is asleep? Whenever I wake my Iphone I see "3G" then it changes back to Wifi...I need Wifi all the time. Yes yes yes I have heard of Insomnia, but I would rather not Jailbreak my phone. Why isnt an app similar to Insomnia on the appstore? Is it illegal/against policies to make an app like this? Thank you!
