Update: The backlight delay has come back, but it's not constant. Sometimes there's a delay, sometimes there's not.
I'm now also having a data in/out issue, here at home under 1X or in town under 1XEV. 75% of the time I try to run gmail, beejiveIM or bbweather...it sends/receives no data at all, just sits there loading, no errors which is really weird. Once in a while it will work fine. Tethering shows no issues like this. I did go from the last OS to an older Alltel OS to this OS within the last 24 hours because I've been trying to fix an issue, maybe that has something to do with it?
