The battle over the nano-SIM standard is heating up with Apple on one side and a group that includes Nokia, Motorola and RIM on the other.

In the latest series of developments reported by The Verge, Motorola and RIM are countering Apple’s nano-SIM proposal with a revised design of their own. This newest design is a compromise which includes elements from both their design and Apple’s. It’s about “80 percent Apple and 20 percent RIM / Motorola” writes Chris Ziegler for The Verge.

We should hear more about the nano-SIM standard when the European Telecommunications Standards Institute (ETSI) meets at the end of this month in Osaka, Japan.
