Some rumors believe that Apple will only launch new versions of the iPod Touch and the iPod Nano at Tuesday's press event. The iPod Classic and the iPod Shuffle are rumored to be on the retirement block. The event could also see Apple make some joint announcements with Facebook, including a long awaited iPad-native version of the Facebook app and possibly an HTML5-based app marketplace that goes under the code name " Project Spartan ." Will Steve Jobs appear at the iPhone press event? As most of you may know, Jobs decided to retire as Apple's CEO earlier this year. Jobs is still Chairman at Apple and could make a surprise cameo appearance at Tuesday's press event. However, it's more likely that this will be the first Apple media event that will feature the current CEO, Tim Cook, on stage to present the next version of the iPhone to the assembled press and the public.
