This is a wacky phone, data is all over the place, one minute 4 bars next 2 then 3 then 5 back to one and then no network -- ALL WITHOUT MOVING PHONE AN INCH, and sure I live in an area with no 4G yet but common this is ridiculous. Coming from its sister carrier network Virgin Mobile, this sucks, knowing that VM is only locked to a couple towers while Sprint is all over (or should be). Also I get better data (which is a surprise) from Virgin Mobile than Sprint. And then the interference is this a CDMA phone or GSM???? I have this bad boy sitting next to my stereo, like I do with my old phone, and it goes all static like it was a GSM phone!
