Hi all, 
  
Thanks Patel for the awesome guide. 
  
New owner of a e6410 - Unfortunately, I have a desktop running iMessage no issues. But for some reason I still cannot get iMessage to work on e6410. 
  
When logging into iMessage, either with incorrect password or a correct password - click sign in - you just see a spinning status bar next to the username? 
  
I have searched and searched. Tried both methods from the troubleshooting area and no luck. Has anyone seen this issue before? I believe other users get errors regarding "Activation" as oppose to my spinning status. 
  
UPDATE: Updating the serial with Chameleon Wizard  SMBIOS area worked! Thanks guys.  Awesome thread! iMessage is now working!
