After debunking all iPad 2 rumors courtesy of its launch last week, more iPhone 5 rumors turn the mill this time. One of these rumors claim that the next generation iPhone will likely have a new aluminum back casing replacing the glass enclosure that the current unit has. Another rumor suggests that the iPhone 5 will sport a new antenna design in the Apple logo itself. Now we all know that initial releases of the iPhone 4 had a major antenna problem that led Apple to their Antennagate design. As with all rumors, take these with a grain of salt as more details will eventually appear.
