While Apple has indeed been giving some developers access to a device known as the iPhone 4S — an iPhone 4 with upgraded internals — BGR has independently confirmed that the next-generation iPhone will not merely be an upgraded iPhone 4 as had been previously rumored. We have been told by a reliable source to expect a radical new case design for the upcoming iPhone, though we have not been given any additional details surrounding the design of the new iPhone case. What about a release, then? The consensus is that Apple is going to announce the next-generation iPhone at the company’s annual September event, traditionally focused on iPods, but we have heard it’s quite possible Apple will break tradition. According to our source, Apple may hold an event in the beginning or middle of August to announce the new iPhone, with availability to follow in the last week of August. We’re not sure if that means the iPod event will be moved up slightly, or if this will be an iPhone-specific event. Thisismynext reported earlier that the upcoming iPhone 5 would feature a new teardrop-shaped case design.
