As for your question about the APN fix
If the ROM is posted here in for example Eb's Cm page or moped s port page then the APN fix probly is included, still good practice to put the fix or even just leave the newest fix on our SD card for just in case reasons
Since the new d2lte models have rolled out, certain pages here haven't really been updated either out of lack of time or that fact that no edits are needed anymore......but for any of those Roms I'd always suggest having the fix around as most devs just switched to the d2lte so the apns are most likely not yet included
I believe although I may be remembering wrong but I believe I saw struckn say someone, I think it may have been Stefen, is in touch with the cm team so hopefully at some point cm at least may soon include ours as well, then after that any ROM built from cm should have it, unless the person building removes them and hopefully after that other devs will follow suit
