Question about Nexus 4 back cover replacements
I cracked the glass on the back of my Nexus 4 and ordered a replacement part. I'm installing the new glass back cover today and noticed the part numbers are different.
Original back cover:
E960 M 130401
Replacement back cover:
E960 M 120911
Both covers have NFC
My best guess is that they're manufacturing dates (04-01-13, 09-11-12), but I'm not sure. Also I've read that some covers don't come with all the antennas.
If anyone knows the differences between these two covers I'd greatly appreciate their feedback.
