Why is there an UNTETHER option in aTV Flash program now?

Could someone please tell me why the latest version of aTV Flash has, as the top item of Manage Extras, UNTETHER option?  After waiting 1 year for a new jailbreak we now have the option of UNTETHERING?  Why?

 

Thanks, in advance.

it’s for people that are running 5.3 tethered now they can click on it and their units will be untethered

 

 

 

Correct, but I’d laike to add, they won’t loose their apps by doing it this way,
