You can't. It ain't happening. It's been discussed in threads before.

Even if you switched to the girly little battery in the GSM version, it wouldn't work. The entire chassis of the phone sticks up as far as the battery, and there's not even room for a penny between the chassis and the back (I tried; that's all I had handy). Plus the shape is different...

Of course, if someone wants to post pics to prove me wrong, I'm all eyes. Within a short period, though, I wouldn't be surprised to see a CDMA version of extended batteries and backs. Who knows, some of them might be the original Diamond shape, or different colours.
