Hey, people. I recently was given my dad's old iPhone 3G, with no phone service. I wanted it in place of my Touch, because it has the camera, mic, vibration, and other stuff. Well, when I put it into sleep mode (I.E. Click the button on the top-right of the phone), the WiFi turns off. I've done some Googling, and I've found that it's a "feature," to save battery. Well screw that, I'd rather get my texts when they're sent than not plug in my iPhone for 3 hours. Is there any way to keep the WiFi on, after it's in sleep mode? Yes, I've seen the Insomnia app by Cydia, but I don't want to jailbreak it. Thanks in advance.
