This year’s Apple WWDC (World Wide Developer Conference) is days away, which means the usual Apple rumors are building up. Most of those rumors are about the iPhone, which is expected to bring another hardware update. Among the rumors, is that the new version of the popular phone (and its iPod counterpart, we suppose), will include a 3D graphics chip, which would make games a serious contender in the handheld market, and challenge the DS and the newly announced PSP Go. WWDC kicks off on Monday with a keynote from Apple.
