Mozilla's Firefox OS event is just kicking off, but the company is announcing a number of new details on both the hardware and software front. A first round of apps has been confirmed, and it includes unsurprising selections like Facebook and Twitter — two apps that are essential for a proper mobile experience. There are also the usual suspects in the gaming realm, including Cut the Rope, Where's My Water, Where's My Perry, and games from EA. Other options include Box, SoundCloud, and AccuWeather, but overall it's quite a small selection for starters. The long-term success of Firefox OS will depend on getting more key apps into the store, but at least users will be able to tweet from their new Firefox phones when they launch later this year.
In terms of wireless carrier support, Mozilla announced Firefox OS will be available on 18 carriers total, including América Móvil, China Unicom, Deutsche Telekom, Etisalat, Hutchison Three Group, KDDI, KT, MegaFon, Qtel, SingTel, Smart, Sprint, Telecom Italia Group, Telefónica, Telenor, Telstra, TMN and VimpelCom. That's up from the seven carriers first announced last July.
