reboot... and it's only 4.4.4. Why on God's green Earth would they deploy 4.4.4 when 5.0 is supposed to be ready to roll?

Thanks for the notes!

So.. basically unknown fixes, plus more AT&T bloatware to disable?

I guess that depends on how important you feel VoLTE and 4.4.4 updates are.

Lolipop will be coming soon enough.

Yea... I guess they started the work for this update long time ago and decided to just finish it and release it. The AT&T's version of Lollipop is most likely still a several weeks/months away.

VoLTE + fixes in 4.4.4
VoLTE and whatever fixes that came with the 4.4.4 update are more than likely not part of the lollipop 5.0 or 5.0.1 updates.. VoLTE I'm sure is the major reason for the 4.4.4 update being pushed before lollipop.. VoLTE is obviously going to be a major selling point in the future for all carriers.. leaving it out and just jumping to lollipop would be stupid for AT&T.. once all areas receiving the 4.4.4 update have been rolled out they should start rolling out one of the versions of lollipop.. probably before the end of February so as not to be to far behind Verizon

AT&T is rolling out the update in "stages", meaning you might receive it later than the other customers. I have 2 Galaxy S5's in family, both are on the same plan and are AT&T-branded, however only one of them have received update. Don't worry and give it some time - unless you live in a region where "HD Voice" is already available this update is not "crucial".
