Not sure what I'm going to do. Go for the unlocked HTC One X with the quad core and HSPA + or go with the ATT HTC One XL with dual core S4 and LTE. I'm concerned about the battery life on the LTE version. It seems as if the unlocked version of the HTC One X with quad core will support ATT 3g and HSPA +. Would love to hear people's feeling on this.
