An “iPhone 5” SIM tray that was leaked by one parts supplier earlier this month suggested Apple’s sixth-generation iPhone may not get that long-awaited redesign after all, launching instead with a look that resembles its last two predecessors, the iPhone 4 and the iPhone 4S.

However, a new headphone jack & earpiece component that has been leaked by the same supplier contradicts that belief, and indicates that the new iPhone will indeed sport a whole new look.

Following the site’s report that Apple is planning a 7-inch iPad for an October release alongside the next iPhone, iMore today says that Apple hasn’t finalized the design of its sixth-gen smartphone (commonly referred to as the “iPhone 5”). All of the metal casing and 4-inch display rumors are still up in the air, but Apple has zeroed in on a smaller dock connector, according to iMore.

Many have been wondering what Apple will call the next-generation iPhone. iPhone 5? iPhone 6? iPhone 4G Epic Touch? Or what about “the new iPhone?” After the third-gen iPad, it looks like Apple may be starting to abandon its traditional naming conventions for iOS devices altogether.

Interestingly, Apple has filed a claim with the World Intellectual Property Organization (WIPO) to gain control of the iPhone5.com domain name.

Is Apple secretly plotting to become your next wireless carrier? It could happen sooner than you think. And will the iPhone 5 sport a widescreen 4-inch retina display? It’s a rumor rundown on our brand new CultCast!

iLounge has had decent luck predicting new iOS devices recently, managing earlier this year to correctly prophesize most of the details about the new iPad (although consensus had pretty much agreed upon them already).

Now iLounge is doing the same for the iPhone 4S, and while they echo a lot of the current speculation about a thinner iPhone 5 with a longer 4-inch display, the professional renders iLounge has put together are absolutely top-notch. This would be an incredibly attractive iPhone.

The iPhone 4S is hardly a fatty, but it is thicker than many of its Android-powered rivals. However, thanks to in-cell touch technology and other improvements Apple is expected to make to the sixth-generation iPhone, the handset could measure in at just 7.9mm thick — 1.4mm thinner than the iPhone 4S.

Many have speculated that Apple’s next iPhone will have lightning fast LTE ‘4G’ networking speeds. Chipset maker Qualcomm has been experiencing incredible demand for its next generation  28-nanometer LTE chips, and industry watchers are saying that device markers are having to adjust their LTE product roadmaps accordingly for 2012.

This news could be a factor in why Apple’s sixth-gen iPhone probably won’t hit the shelves this summer if it does indeed come with LTE. Instead, analysts are predicting an October rollout, mimicking the iPhone 4S launch just last year.

Apple has filed for all sorts of patents related to 3D technologies over the years, sparking speculation that the company will one day bring us 3D-capable Macs and iOS devices. But evidence that it’s about to get serious about 3D technology for iOS devices comes from a recent job listing on its website for a “Computer Vision specialist to strengthen its multi-view stereo research group.”

Apple CEO Tim Cook will announce the company’s second-quarter earnings on April 24, and according to one analyst, it will report sales of 33 million iPhone, 12 million iPads, and 4.3 million Macs. Sounds like another great quarter, but those predictions are, on the whole, a little less than Wall Street is anticipating.
