Apple is notorious for creating devices with parts that can only be repaired or replaced by Apple themselves. It looks like they'll be changing things around and making devices even more company-specific with their iPhone 5.

Two of the new features seem to be a nano-SIM card and a smaller dock.

The smaller parts probably indicate that Apple is trying to use up every inch of the taller, but thinner next-gen iPhone handset.

German T-Mobile locations have received shipments of the smaller SIM cards, reports iFun.

Dear partners,You will receive today a new generation of SIM cards for the latest generation of smartphones that come in the near future on the market. Sort your SIM card please first not in their cards in hand and give it not out to customers. We will inform you shortly about how to proceed," said the letter that accompanied the nano SIM cards.

The iPhone 5 is the only upcoming smartphone rumored to be using a smaller-sized SIM card.

The smaller dock has been featured in a number of supposed iPhone 5 component part leaks. Next-gen Apple devices such as the iPad Mini and new iPods will all be using the newer 9-pin dock instead of the standard 30-pin dock connector. 

While this has many speculating that all current iAccessories and cables will be rendered useless by this dock size change, an accidental posting on Apple's online store, according to AWhiteDot, revealed that there could be a 9-pin-to-30-pin dock converter connector. If true, this would mean that the new iPhone would still work with older accessories.

Apple will reveal the iPhone 5 at a press conference on September 12. and the phone is expected to go on sale on September 21 through AT&T, Verizon, and Sprint. It will have a 4-inch screen, be 4G capable, and run iOS 6.
