Yep, that would be what happened. Yeah, the iPhone runs smooth (and for most part, I loved it), but the fact I can\'t SMS / MAIL /NOTEPAD / SAFARI all at the same time, without all of them closing, except for one annoyed me to no end.
As for background processes slowing shit down. It does to a certain degree, but not nearly that bad. Look at other OS\'es and how they\'ve managed it. Really, there is no reason for Apple to have not implemented this.
