iPhone 4 unlock is available for iPhone 4 now. Again, Ultrasn0w has done it again. Do not be mistaken by jailbreaking iPhone. Unlocking iPhone means unlock from the current telcos. In Singapore, we do not have this problem as all our iPhone (bought in Singapore are unlocked).

However, if you bought your iPhone elsewhere and cannot use current SIM card, I suggest you head over to Engadget to verify if it can be unlocked using this software or not.

In the meantime, watch the unlocking process.
