ONLY WORKS ON TPU CASES, NOT SILICONE. I got my ipt4g yesterday, and it is perfect. I had already bought two cases, one silicone frosted white color (absolutely horrid!) and a crystal clear tpu case to show off the unique skins I bought. Well the damn thing would not fit, so here's what I did. 1. Take a sauce pan or small pot and fill about half way with water. 2. Bring water to a boil and TURN OFF. 3. Pop in TPU case and swish around for 2-3 minutes, making sure not to let it sit on bottom of pan. 4. Remove case, it will be VERY HOT! 5. DRY OFF QUICKLY and put on ipod. 6. Press and mold it, and let cool. It should fit perfectly. Bon Appetit! Caution: My tpu case was clear, not sure what will happen to colored or printed tpu cases. TRY THIS AT YOUR OWN RISK. KIDS DO NOT TRY THIS AT HOME WITHOUT PARENTAL SUPERVISION.
