As xmr405o pointed out the version number, even though the same as the leaked version, could be a combined OTA of all the ones that were leaked. Although it would be odd imo to combine all the OTAs and throw them into an older version number. Then again we only know the version numbers by what was leaked. So 5.5.893 could in fact be 5.5.893, 5.6.893, 5.7.893, 5.7.894, and 5.8.894 all combined. No one is suppose to really know the revision numbers. That's why I was mentioning comparing the radio and kernels once the OTA is officially out. Some devs are going to have to pick at the OTA for us and let us know if what they released is old or new.
I didn't read the post on Droidlife so I could have jumped the gun on that. Since the PDFs displayed 5.5.893 as the update I had assumed this was an old PDF and something that someone mistakenly found and is spreading around. Considering that the print does show 1211 it is possible this is a new pdf and in fact could be for the OTA. I still think there's no official announcement yet but it looks like this will in fact be the OTA everyone is waiting for.
I am already on leaked 5.7.893 so I am sure I wont be able to apply the update. However I still want to see is the 5.5.893 is the same as the leaked 5.5.893 or if the 5.5.893 is the combination of all the leaked OTAs. All we gotta do now is wait and hopefully get some good responses from those finally getting an official OTA.
