How to Unlock iPhone,iPhone 4,3Gs / 3G without Wi-Fi Using Ultrasnow

How to UNLOCK IPHONE or IPHON4. I will unlocked iPhone 3G, 3GS and iPhone 4 using this method and I’m sure it will work for you. You dont need wi-fi connection to unlock your phone, it’s an offline unlock to get your phone activated and useable with iTunes and any SIM card different from your home network provider. To unlock your iPhone 3G or 3GS or iPhone 4, you must first jailbreak the phone and upgrade to iPad baseband. If you haven’t done this, this tutorial won’t work for you and you may not be able to use your iPhone with another carrier.

I’ve done this countless times because each time I upgrade my firmware or decide to set up my device as new, it automatically locks. The phone is locked to AT & T which is not even available in my country. I can’t even use any SIM card here with it and connecting it to iTunes requires activation and since i cant do that, I have no choice but to hacktivate it
