Happy Wife... Happy Life... I have never been married, but even I get it... But boy I would hate my Prevail running stock. Junky apps taking up almost all the room, and if you are lucky you can add and run only one more app. After that it is a game of remove and instal just to use.
Any idea "why" it is upsetting to her? It is legal to do it.
I am sure that Boost can "see" a rooted phone in their system... So if they did not "allow it", they would/could kill your line....
