May 30, 2012 1:37 PMby Plughie,I don't have a CDMA phone. My phone currently auto-switches to Edge, and there's no reason to remove a feature that is being handled automatically by my phone and is available on other devices using the same OS.
Perhaps when Edge is unavailable anywhere in the world, it would be worth removing the switch. But until then, it serves a useful purpose.

There once was a technical workaround to the problem of NIMBY (Not-In-My-Back-Yard) neighbors, but it was removed in a recent software patch.

My laptop doesn't go to sleep mode. I have tested this, and if it is plugged into the Apple supplied charger, the wi-fi doesn't go off, but if it is plugged into the computer USB interface, even if the computer is actively in use, it still shuts off the wi-fi after a few seconds. Charging continues, however.
That would indicate the USB port is not putting out sufficient power to both charge the phone and keep the WiFi radio alive. Given the choice, the phone should try to charge. Doing otherwise could actually result in the battery being drained while connected to USB if the available power is too low.
Good thought. Maybe that is the case as the USB ports are only rated for 500ma. Works fine for overnight charging.

Even with iOS 5.1.1, certain carriers, such as AT&T, no longer allow disabling 3G because they are phasing out their 2G service to make room for 4G (LTE)
