Cancel your plans for Oct. 4: That’s the day Apple will roll out the iPhone 5, sources tell AllThingsD. That website had previously reported an October unveiling, and Mashable’s prediction of Oct. 7 wasn’t too far off, either. Gizmodo notes that the date is a bit later than had been expected, and adds that iOS 5, iCloud, and new iPods will also likely be launched. According to AllThingsD’s sources, the iPhone 5 would then be available to buy within a few weeks. This will be a particularly important event for Apple, as new CEO Tim Cook’s first big product rollout.
