Hey Kashar, I tried looking at your pictures, but it's still very difficult to see the screws. Could you light up the bottom of the phone with some good lights (bring the bottom of the phone close to a desk lamp, etc.) and take a photo with the "macro" mode of your camera? That will give us a much better idea of what kind of screw type we're dealing with.

Original iPhone 4 images on Apple's site had star-shaped screws on it -- are these the screws found on your phone? If so, they're a variant of the tamper resistant Torx Plus patented screws. They are basically star-shaped instead of six-sided, with no post in the middle of the screw head.

If so, you can (very carefully!) use a small flathead screwdriver to turn the screws. We haven't done it ourselves with such a small star-shaped screw, since all our iPhone 4s had normal Phillips screws, but it should be possible.

We published a blog post today that explains in detail what these "Pentalobe" screws are, and why Apple is using them in their devices. You can use our iPhone 4 screw replacement guide and Liberation Kit to replace these diabolical screws with standard #00 Phillips units!
