We already know that the iPhone 5 is the most anticipated gadget of 2012, and we’re pretty sure that we’re actually going to get an iPhone 5 this year, so all that remains are the details. Luckily, we’ve got just the thing to sate your rumor appetite.

According to 9to5 Mac, the iPhone 5 is getting ready to begin production. Based on previous iPhones, this would likely indicate that the device will launch this summer.

The tip comes from sources inside Foxconn in China. Apparently, these are the same sources that went against the grain when regarding the last iPhone release and said Apple was planning on launching the 4S instead of the expected 5.

Not only do we get info on a possible production timeframe, but the sources say that multiple sample devices already exist, but they are all different from on another to varying degrees. Although they couldn’t say for certain which of these prototypes will most resemble the final product (if any), they did mention that all of them have certain features. This includes that big 4+ inch screen that everyone has been clamoring for.

This corroborates other analysts who predicted that the next-gen model would have at least a 4 inch screen. Of course, Apple has been rather stubborn about that 3.5 inch screen size.

Although some recent report said that the new iPhone will in fact be slimmer than the 4S, it won’t have a teardrop shape according to the Foxconn sources. The teardrop rumor was one of the most prevalent ones preceding the iPhone 4S release.

Whether or not this proves accurate, we can be assured that the iPhone 5 is going to be one the biggest devices in history. It might even be available on T-Mobile, too.
