I have read over the years that it is completely not useful and can be disabled to save battery life. I've also heard that if you disable it, your service will suck in some areas because some towers require it. I just got another V9M and the battery life sucks - of course - and I can buy a battery meant for another phone which is more powerful (about 20%) ... but if I can just disable some stupid thing, that'd be easier. . .

Thank you GFY gurus
