I agree, I bought a 3M microfiber eyeglass cleaning cloth from Walmart for about $3.00 and it works great, no smudges and small.I used to! However, the best cloth to use is called the magic cloth. Sharper Image used to sale them. It is a "microfiber" cloth that works beautifully. I'm sure that you can find microfiber cloths at Wal-Mart. I think it works way better than the cleaning cloth that came with the iPhone. Even after using the cleaning cloth that came with the phone you can still see the smear marks from wiping it. Your screen will look like it has never been touched after using the microfiber cloth!
