It's already been available -- and hacked -- for a a few days now, but iPhone firmware 1.1.2 has finally reached iTunes, the natural home of all things iPhone. We honestly haven't noticed much more new since we started poking around -- the .m4r ringtone hack seems to be back, and custom ringtones are now broken out in their own list -- but we know you can't resist the siren call of the latest version number. Go on, you'll be fine -- and it's not like getting back to 1.1.1 is any great feat.
