Don't use it. If you don't use it it doesn't do anything. You have to be signed in to use the twitter/facebook functions.
I have never used either twitter or facebook, they simply don't appeal. I agree it would be nice if they could be disabled, but Apple is a dictatorship whose users aren't allowed choices. It's been that way for years.Its a shame. I wish the first option was turn Facebook / Twitter on? and if you answered no, there was no reference to these features anywhere.
I really think this is not the case but I'll be annoyed if it is. I am hoping it runs similar to Android where you have an option, when you want to share a pic or something, to choose twitter, facebook etc.My only hope is that iOS6 is not constantly suggesting I tweet this or like that, or share this on my wall.
I think that's a long way off and enough so that by the time it does happen, Apple won't feel like their integration was all for nothing. Think about it, if you did something that was good for a few years and it suddenly became obsolete then would you really see it as a waste?I'm sure I won't be the only one laughing when Facebook finally jumps the shark, and then apple has to go through and remove all the Facebook hooks from their software.
