in Apple


R-SIM IV for 04.11.08/04.12.01 was based on SAM Unlock. But unfortunately Apple has patched their activation servers. So this will no longer work.

Earlier today I blogged about ApplenBerry releasing Gevey Ultra for 04.11.08 & 04.12.01. Another Chinese manufacturer is releasing R-SIM IV to unlock iPhone 4 on basebands 04.11.08 and 04.12.01.

Follow one of these tutorials to jailbreak your iPhone 4:

The price of R-SIM IV is less than the price of new Gevey Ultra. R-SIM IV costs only $19.99 whereas Gevey Ultra costs $49.99. We don’t know any other differences between R-SIM IV & Gevey Ultra.

Where can I buy R-SIM IV to unlock 04.11.08 & 04.12.01?

If R-SIM is exactly based on the new Gevey Ultra, then it’ll work with blacklisted iPhones.
