Well I haven't rebooted yet, so we shall see. I've noticed the same thing with the wifi icon as well. If I end up needing to reboot, I'll wipe both caches and report back on what happens. Yea, progress though!
EDIT: I just had a spontaneous reboot (13ish hours up time from the flash of cornerstone 4) and everything came back just fine. I was on 3g at the time, and after reboot, 3g works, wifi works and switches back and forth like normal, nothing seems glitchy. I did not do anything other than let the tablet reboot on it's own and then check everything out (no wipes or anything like that). I'll have to give this cornerstone my "working terrific" stamp of approval.
Are you on build 66?
