Hi! I just got an HTC 8X a couple days ago (switched from Galaxy Nexus) and I'm on a 2GB data plan since I use my ipad for nearly everything; but I heard a lot about windows phone not keeping a wifi signal when it goes to sleep. So does this mean that even when I see the wifi logo in the top when I'm at the Lockscreen, its still not working? When wifi is enabled, does it disable 3G automatically? This is elementary but I didn't want to go over my data because the OS can't turn off 3G when in wifi.
