I'll be really disappointed if this "6C" is a low-cost model. I've held off upgrading my personal phone because I dislike the 6 and 6+ form factors so much.
Same here. I hope its at least an upgrade from the 5s. I won't care if its a downgrade from the 6S's.
Ill also, maybe, upgrade to the 6s 4.7 if they move the power button from the side to the top again, even though 4.7 is still too big for me.
4.2 - 4.4 inch would be perfect.
