Sherrif Hashim, The Dev Team hasn’t shown any response on the ultrasn0w unlock since last year from the iPhone 4’s baseband after 01.59.00. Months back when the iPhone 4S released, hackers claimed that they will unloch the iPhone 4S baseband either by SIM interposer or by software. Today a SIM interposer released named R-SIM will now unlock the iPhone 4S on iOS 5.1 and iOS 5.0.1.

To run this new R-SIM your device is not needed to be jailbroken and it will run on all the GSM carriers around the globe. The main degrade thing is that it won’t run 3G but will run on EDGE. Every one around is yet recommending including us to not buy it because no one yet has checked it out so wait.

The steps to activate via R-SIM are easy. After inserting it to the iPhone 4S, select your county and carrier, and dial 112 mode to activate so its quite simple. The R-SIM actually is very expensive too comparing to the old SIM interposer, the Gevey SIM. Gevey Ultra costs $19.99 while R-SIM costs $57.99. You can buy the R-SIM from EachSupplier.
