I bought my Nexus 5 from Tmobile (north america), found out that I have very little (read: zero) coverage between my home and work, so I had to cancel. I went ahead and paid off the N5 and switched to AT&T.
Oddly enough, the myAT&T screen shows me as having a LG 821, which, I believe, is the international version!
I found that concerning as I thought Tmobile might have worked better for me if I had the correct phone... but my bootloader shows D820.
Anyone else have the same quark on their myAT&T page?
