ZTE announced earlier to bring its first Firefox OS phone this month on the ZTE store on eBay in the U.S. and UK. But it has released a global version of the phone, which is already available from Telefónica in Spain, Venezuela and Colombia. The smartphone cost $79.99 (£59.99) and comes in orange color. And, guess what? It’s unlocked; which means users are allowed to use the phone on any network.
