Well if you are running the latest one from mydroidworld then they are the same. And that one was released yesterday.I received tweet the official has market issues also.
Their is no reason to update to the new one its the same thing actually I would stick with the leaked version since it doesn't reflash your bootloader. allowing you to sbf back to 2.1 if needed
DO NOT DOWNGRADE TO 2.1 SBF FROM THE 2.2 OTA, THE KEYS/ SIGNATURE CHECK HAS CHANGED. YOU WILL BE BRICKED IF YOU SBF TO 2.1 FROM THE 2.2 OTA! UNTIL WE GET A 2.2 SBF LEAK. (This leak is safe to sbf from, as it does not include baseband, kernel or bootlodear update.) Sent from my DROIDX using Tapatalk
