That's quite a line-up they have! I have a Elephone S3 pro, two day battery is really great when traveling, no worries. I'll strongly consider an Ulephone next..
Wow - what a great find! I'll be keeping track of that crew for my next phone!
('tho they don't seem to currently support Verizon network)
Yeah I had to go with a TMO reseller here and most of the time I am using calling-over-wifi to make up for TMO's spotty coverage.
