Wish I had seen your comment before gently prying up the battery and pulling the white antenna cable straight out of its tiny gold connector. Down to wifi-only as I await the replacement cable from eBay.

I just did the same thing. Wish I had seen your comment earlier!

Well that sucked. Really wish you had mentioned the antenna cord being taped to the side of the original battery. I yanked it out when prying off the glued down battery and ended up with a wifi-only device. The Nexus 4 battery replacement guide could really use an update.
