Carriers are doing the math. Less than 9% of wireless connections are 2G or 3G. If you're on a local carrier then you'll most likely hang on a bit longer. More importantly, is that if your cell phone is 3G ONLY then you need to upgrade your phone. The phone may work with your local carrier but it'll be a brick if you roam into other networks... My understanding that this will impact ability to call 9-1-1 as well. Something to do a little research on. Check your carrier and check your device.
