Just received on of these as a gift for Christmas, and I've been looking ALL over for a way to disable the 'cell phone' aspect of it to increase battery life. 'Cell Standby' using the majority of battery power. - I know someone else just put up a post recently asking how to do this with a 7" version, and people said to 'root it', but it looks like there's no way to 'root' this model? Looking around the tablet's harddrive/memory, either directly on the device or on PC, I can't find any APKs having to do with telephony. - And while putting it in 'Airplane mode', it looks like there's no way to manually turn on the Wifi while Airplane mode is on. Has anyone successfully removed the cell phone stuff from this model? Or found an app to disable it somehow? Also, this touch screen is driving me crazy. Is there a trick to scrolling that won't accidentally select something I'm scrolling through? It happens all the time.
