Good news for AT&T consumers looking for the next big smartphone experience, the iPhone 5 HTC One X+ is coming!  It appears that a quad-core Tegra 3 powered PM63100 has made its way to the FCC, presumably en route to Ma Bell.

According to Engadget, documents show the handset offers AT&T’s bands 4 and 17 in addition to 2 and 5 of LTE, indicating that we’ll soon have our cake and eat it too.  For those keeping track at home, we don’t have a quad-core smartphone with 4G LTE support, yet.
