For Mac-focused bloggers this week, the biggest news by far has been the upcoming 3G iPhone, the old iPhone and AT&T’s iPhone pricing plans. Bloggers and readers have been poring over the details — AT&T launched a mini site complete with FAQs — and most everyone seems to think the $199 entry point will generate millions in new sales around the world. AT&T will start selling the new 3G iPhone bright and early July 11, and the company is recommending that brand new prospective iPhone customers come prepared with a photo ID and Social Security number for a credit check.
