Ummmmm, nope.

Love:
+The case fits better together in this incarnation. The top of the case slides into the body perfectly flush.
+The openings at the bottom form a wonderful speaker box for the iPhone 4. I'd almost recommend it for that fact alone.
+Red! Just the color I wanted!

Hate:
-The battery in this case doesn't seem to last as long or re-charge as much as my origial Mophie. But that could be perception since the battery in the iPhone 4 itself is such a vast improvement on the 3G. Bigger/better battery means more drain on the Juice Pack.
-"Soft Touch" is showing wear and tear already! I just bought this and I treat it no better than my old Mophie Air. There's something lost is this new design.
-Horrible, horrible USB cord!

I'd read reviews in the past about how bad Mophie's USB mini plug is but never experienced it for myself. Now I know. It's a good 3 feet too short. It still wiggles around in the jack on the case. That was a minor problem I had with my original Juice Pack but nothing ever snapped off so it wasn't a problem until now. The small end of the USB cord became loose after 3 months. Forget trying to use the phone while syncing/charging... I mean c'mon... 3 ft. cord!... it wasn't going to stay in unless the phone was perfectly still. Then, one day after I dared to move the phone while charging, I noticed the cord wouldn't even plug in straight, only to find that one of the pins in the jack had broken. GRRRR!

I will say this though. Mophie's customer service is fast. I just put in a request for service on Tuesday and they have sent me an electronic return label the next day. Hopefully this will address one of my issues with the Mophie Juice Pack Air for the iPhone 4.
