This thread is for the purpose of identifying the resolution to this issue.
To begin with I'll start with asking for details from those of you who are encountering the issue and also those who are not.
What I want to know is, what software you were running and also exactly how you got to that version. For example ist is not sufficient to say you did my S-OFF upgrade, I also need to know the device (wifi or 3g) and version of the upgrade you used and whether you switched from a different version of the software to your current version.
For example, something like this:
Not Working: US Wifi Flyer, S-OFF, originally upgraded with the WIFI package built from 3.55.405.1 3G package, re-flashed with the US wifi OTA.
Casual observation seems indicate that it is all or mostly Wifi flyers that are affected.
