The iPhone sat firmly in the center Apple-focused blog world this week. Apple, of course, delivered an iPhone 3.0 OS sneak peek to the press, which led to a stampede of blog activity.

Meanwhile, the latest AT&T rumor has the company offering iPhones for sale without massive two-year service contracts — but without the sizable price subsidy, either.
