AT&T HTC One X = Dimensions 134.8 x 69.9 x 8.9 mm
Case = (137 cm x 70 cm x 10 mm)
Looks like it would be a tight fit, based on the 2nd dimension but I think with enough ductape you'll get it right in there ;] Its only two dollars though, I'm sure you can go find enough quarters on the street today to get one just to find out. I prefer the dings all over my phone. Makes it more personal knowing how many times I died a little bit on the inside when I Dropped it <\3.
