Ugh. I'm having huge problems with my phone. Can someone tell me which of these I should be downloading for my Sprint 5S? I thought it would be iPhone6,2_8.1.2_12B440_Restore.ipsw for 5s GSM+CDMA,, but when I try to restore from that, it tells me it isn't compatible. My phone has been messed up for the past couple days (11GB of "other" leaving no room for my music) and I need to get this fixed before Apple stops signing.
