Apple's WWDC is right around the corner, but this hasn't stopped the continuous stream of discoveries, leaks and rumors surrounding the next generation iPhone. This photo of a banner hanging at the WWDC venue all but ensures the conference will focus on iPhone 3.0 and the AppStore.

Several new features are now on the horizon. BusinessWeek reports that Apple has already included code in iPhone OS 3.0 that would allow users to directly share apps with each other. Analysts have even suggested that the person sending the app could receive a commission from the AppStore.

The iPhone Dev-Team has confirmed that updating to iTunes 8.2 will make the current versions of QuickPwn and Pwnage Tool inoperable. They are warning users who wish to jailbreak iPhones to wait until the new versions of their tools are available before upgrading iTunes to the new version.

The Dev-Team plans to release updated jailbreaking software after Apple makes a public release of iPhone OS 3.0. An update to the unlocking software yellowsn0w will also have to wait.

According to reports, the PTCRB has tested and certified four new iPhone models for use on GSM operator networks. The four models have four different storage capacities, ranging from 4GB up to 32GB.

If the reports are true, Apple is likely differentiating the four models not only by changing the amount of flash memory. Previous leaks have indicated that Apple plans to offer modified software on each model to allow different levels of functionality based on the hardware and price of each device.

More photos of iPhone OS 3.0 have been released, this time from a user in Hong Kong who claims to have seen a prototype. The images aren't the best quality, however they confirm many of the recent rumors swirling around the upcoming model.

Among other things, the pictures demonstrate digital compass, voice recorder, horizontal messaging, and MMS functionality (video and photo messaging). Many of the images also show details about how auto focus will work with the new higher-resolution iPhone camera.
