Well, folks, its this time of year again. Tomorrow at 1:00 p.m. EST/9:00 a.m. PST, Steve will be donning the blue jeans and black turtle neck and heading for the stage of the Moscone Center. As this year’s World Wide Developer Conference gets ever closer, it’s time for a rumor and speculation round-up.

For the most part, the speculation this year has hovered around four items:

1. 3G iPhone
2. .mac
3. iTablet
4. Mac OS X v10.6

Read on for all the recent news regarding these and other possible happenings at WWDC ’08.

With all the WDDC rumors flying around Worldwide Developers Conference 2008, it has become tough to keep track of them all. Here is a list of recent rumors, and details on their credibility.

1. 3G iPhone – Is the Pope Catholic? I think that it is safe to say that this is the only rumor that is definitely going to become a reality. Now the only question is what it will look like and what any changes to the OS will be. Personally, I would love the iPhone to look something like this. Two of the biggest proofs behind this rumor are a lack of iPhones (“Currently unavailable”) on the Apple website and the fact that AT&T are not allowing their employees to take vacations for a period of time this summer, supposedly around the 3G iPhone launch. Also pointing to 3G are supposedly leaked screenshots of the 3G iPhone, strange new terms on shipping manifests, dates supposedly being announced, strange looking icons buried deep within the iPhone SDK, and announcements coming straight from the horse’s mouth, or in this case, the mouth of the Telefónica Europe’s CEO.
