Apple this weekend has tipped its hand early and provided clues as to its future iPhone upgrades. Pandav, the developer of the iPhone train tracker app iBART, reports seeing the previously leaked iPhone 3,1 hardware ID showing up in logs identifying those using the software. The previously unreleased device has been seen as early as the March beta of iPhone OS 3.0 but now appears to be in live testing online, keeping in step with Apple's past practices of testing iPhones' Internet usage several months ahead of release.
