Phone 4 Baseband Chip Downgrade from 4.11.08 to 4.10.01 Service Now Available

I am not selling this, But providing information to the interested persons of these options they can do themselves or pay for someone to do.

Baseband downgrade from 4.11.08 to 4.10.01 via chip replacement is now possible on iPhone 4.

My team and I would like to present sort of a good news for those who are currently stuck on baseband 4.11.08 as we managed to downgrade an iPhone 4′s baseband from 4.11.08 to 4.10.01 on 22 October, 2011.

However, it’s still now possible to downgrade to 1.59.00 to make it unlockable with ultrasn0w.
It’s similar to our baseband chip replacement service for 3G and 3GS, but this method requires two different chips to be replaced – the Infineon X-GOLD 618 processor chip and the 128MB NOR flash chip.
Once your iPhone 4 baseband has been downgraded to 4.10.01, you can then unlock it with a Turbo SIM.
There are a few tiny setbacks with this method – your iPhone serial number and IMEI will change. That means you can only hacktivate (activate) it with redsn0w or use custom hacktivated firmware in order to do a full restore. However, it is still possible to use original firmware to restore your iPhone 4 if you ever need to; unlike iPhone 3G/3GS on baseband 6.15.00 which doesn’t allow you to restore at all.


If you are stuck on baseband 4.11.08 which presently cannot be unlocked with ultrasn0w or a Turbo SIM, this is the service for you. It is similar to our popular iPhone 3GS baseband chip replacement service.
Once your iPhone 4's baseband is downgraded to 4.10.01, you can unlock it with a FREE Gevey Turbo SIM which is included in this service.
There are two chips that need to be replaced in order to downgrade your iPhone's baseband.
