At this point in the rumor cycle, it would be easier to list things we don’t know about the iPhone 5C. Apple’s lower-cost model will likely be announced alongside the 5S on September 10, and it will probably look a lot like the iPhone 5. The main difference is the plastic shell, which will reportedly come in several colors.

We’ve seen leaked parts for just about every 5C color already, and now some closeup images have surfaced of a blue shell.

What you see above comes from Tactus, a reliable parts leaker that was one of the first to go hands-on with 5C parts earlier this year. The company’s sources are saying Apple will offer the 5C in white, black, red, yellow, blue and green. The iPod touch currently sells in black, white, pink, yellow, blue and red.

We’ve seen lots of pictures of budget iPhone parts in recent weeks, but these images from case maker Tactus show us what the device will look like when it’s fully assembled — complete with a display, a camera and flash, buttons, and a Lightning connector.

I have to admit, I hadn’t heard of case maker Tactus until last week, but in the space of just a few days it has published an unveiling date and specifications for the fifth-generation iPad, the plastic casing for Apple’s rumored low-cost iPhone, and now the fifth-generation iPad’s new aluminum shell.

Remember that fifth-generation iPad mould that we reported on earlier this week? Well, its source has now obtained what is believed to be the casing for Apple’s rumored low-cost iPhone.

It’s made of polycarbonate plastic just like the iPhone 3G and the iPhone 3GS, and it will reportedly pack a 3.5-inch display like previous iPhones — yet it’s both taller and wider than the iPhone 4S.  It may also get its grand unveiling this October.
