Blackberries are kind of starting to die so they maybe more like the Eldar. I's say Androids are more in line with Chaos. Pretty much the same in performance and options, but not quite the as much a single Deity cult.
Necrons of course would use the 1980s Cellphone. Large, unweildly, not really a lot of options, but they would continue to use it because that's how they did it in their day!
