LOL, iOS 7.1 is updated BEFORE AT&T 10.2.1
hahahahaha, I own both iPhone and Z10 and as I bet on myself, iOS 7.1 is available BEFORE AT&T 10.2.1, guess what?
what a joke! I am a BB loyalist since Bold 9700, never own an iPhone until last year because I was sick of BB. Got Z10 due to AT&T promo of $100 old smartphone trade in, so I trade in all my old BB for a Z10, and now Z10 still lacks behind.
I love Z10, no doubt, the best BB, but with their lack of SW update, I think I am done.
OMG!! for sure, Z10 is my last BB phone ever.
Newest and latest OS is my thing, I even sold my Tab 2 10.1 and get Nexus 7 because I can not stand on Samsung lack of SW update as well.
anyway, don't tell me to get Sachesi and such, because I only do official OS.
