Ok guys...nothing like a good debate. Like MattyP (whom I hold in high regard)...no guarantee. Unlike MattP, I don't think JB will install over ICS. I base this on one thing: An OTA does three things when it is received (1) it checks the MEID of the phone to see if the phone is to be updated, (2) it checks to see if the phone is rooted and (3) the most important in this debate, it checks the system version on the phone. An update is designed for a specific system version to be "updated from". If during this check the system version present on the phone differs from the system version the OTA is designed to update then the update will not be successful. The OTA to JB will be looking for system version .211, if it finds any other system version the update will fail. We ought to start a "poll" here.
