Aparently if you bought it at the Boost store you may be elegable for an upgrade, I don't know about other authorized retailers. I had bought the Volt a year ago from the same location.
I didn't want to buy one and I wanted to keep it cheap. The Samsung Galaxy J3 has 1.5GB RAM and would have been $80.
That v10 is sweet! I wonder if Boost will get it.. lmao. I might look at the G3 when I get my tax refund... as long as it's rootable and has CyanogenMod. Since Marshmellow requires a kernel mod and unlocked bootloader... And I'd rather have a dark theme on CM then LG's white menu background.
