Mine finally worked. I kept trying pulling the battery out and keeping it out for a minute or so and then putting it back in and then going to "update Android" through system updates with either 3G or 4G enabled and I kept getting nothing so by process of elimination, I enabled wifi, yanked the battery, kept it out for a minute and then put it back in and rebooted and went back to "update Android" through system updates and BAM, there it was.
Now for the sake of curiosity, I wonder if all of us that have the Epic's that seem to always be way over 50% without a signal unless we either toggle airplane mode or do the PRL update tricks are the ones that were having an issue with getting the update? I have one of those flaky Epic's with the bunk firmware as well and I usually have to PRL update daily so my phone doesn't keep searching for a WCDMA signal.
