About half the time after turning off Wifi on my Droid, data (1x/3g) does not come back on. The 1x/3g icon doesn't show up, and I can't access data. I have to reset my phone in order to get data to come back on. I run into the same problem when I shut data off in settings, and then turn it back on. About half the time it requires a reset to come back on. Just now, I turned the screen on after a few hours of inactivity (wifi was off, data was on in settings) and data wasn't working. I waited a few minutes, but it didn't come back on.
This only became a problem after upgrading to Android 2.2 (FRG22D). I'm running the official build that was installed as an OTA update a few weeks ago (the second Froyo update that Verizon pushed out).
Has anyone else been having similar problems? It's more of an annoyance than anything, but it would be nice not having to reset my phone a few times a day.
