Re: Not just cheap phones it seems...
I don't think so. I'm pretty sure that the "Wireless Update" app specified was the one that popped up during the most recent (and first) Cosmo update.
As an early Indiegogo backer I was one of the first to receive a Cosmo so I'm expecting many further updates to what is, essentially, a perpetual work-in-progress.
Up until now, I've had no complaints.
