This happens on mine with facebook book being installed by samsung themselves, i dont think i get the mobile services manager thing. And mine isnt from a carrier or locked to one
Ive seen some things (totally unrelated mobile apps) make ads optional. I think its a good idea if youre iffy about having them but do need them to keep the site up, im sure people would be happy to enable ads to support these types of sites. Plus cant be any worse than the shite youtube has for ads
