By -

R-SIM mentioned a couple of weeks ago that they were working on unlocking iPhone 4 baseband 4.11.08 and guess what? They have finally completed the solution to unlock iPhone 4 baseband 4.11.08 & 4.12.01 in the form of  R-SIM 4.

R-SIM IV has finally been released to unlock iPhone 4 on all basebands including the infamous 4.11.08, the one that had kept thousands of users stuck with an expensive iPod touch. 

Maypalo first mentioned about R-SIM IV unlocking solution for iPhone 4 back in late March, after hitting many delays the developers behind this have finally completed the unlock for iPhone.

You can now unlock your GSM iPhone 4 with the new R-SIM IV. will work for iOS version 4.1, 4.2, 4.2.1, 4.3, 4.3.1, 4.3.2, 4.3.3, 4.3.4, 4.3.5, 5.0, 5.0.1 and 5.1 with modem firmware 1.59, 2.10, 3.10.1, 4.10.1, 4.11.08, 4.12.01. Be sure to check your firmware version before purchase!

Although we now have the solution to unlock the infamous baseband 4.11.08 via R-SIM 4 and Gevey SIM, did we seriously need these after the free unlocking solution?

  1. there is a simple answer applenberry and eachsupplier just copied the the method of great chinese hacker “loktar_Sun” on their interposer sim. one answer is fuck applenberry and eachsupplier and others who claim 04.11.08 unlock after him.

  2. This is what i call bad timing, r-sim And gevey had mounths to release An unlock And make alot of money And now they will Sell shit cós there is sam unlock there is free,ahahah

    Shahdat i agree with you fuck appleberry and the others they are just copy cats ….how convenient that “all of a sudden” they have cracked the baseband.. it will be interesting to see when apple plugs this hole if the sims will work …we will wait and see!!

    • I agree fuck appleberry and r sim they just think about the money.

      I hope no ones buy those sims. We really appreciate Loktar_Sun and his app Samprefs.

      Long live the king Samprefs (Y)

  4. Hi Farnham.my iPhone 4 unlock successfully by Sam. Now want to know can I use any sim of my country & upgrade 5.0.1 to 5.1 .post or comments pls

  5. explains why its so cheap compared to when the rsim 3 initially came out.

    If they’ve copied loktar method then that means that the r-sim isn’t needed after the unlock.

    I’ll wait and see.
    Good to see some options popping up though.

  6. I believe this HOLE/EXPLOIT will get patched on iOS 6. Expect new system file structures with iOS 6 which even the save Lock-down files wouldn’t work.

    I would still love to buy Gevey if they going to lower its price to $19.99

  7. Since SAM method doesn’t work for me, as i do not know my original carrier which my iphone locked to, this might be solution 4 me. Congrats 4 those who able to unlock their iphone using SAM :)

    • mate finde your orriginal carrier by seral number and model… Just google it, or use itools.hk/tscms to see you original carrier… Rest is easy job, just follow tut on maypalo.

    —————If you are a AT&T customer: PLEASE READ—————-
    Don’t go for either paid or free solutions. Call AT&T and get your iPhone factory unlocked for free. Let me know if you need any details

    • I am from Bangladesh my brother gave me the which was AT&T , now tell me how to get free FU from AT&T

    • Help me on this issue i dont know how to unlock it from at&t. Actually it required user name but i dont have dat!!! do i have any other option???

  9. It’s pretty hilarious, waiting such a long time for an unlock and all of a sudden when the SAM Unlock is released for free, all the interposers arise. Well mates of R-Sim, Rebel and Gevey, and magically they now need the phone to be jailbroken. I hope your sales are flat zero. Delaying for such a long time a release.

    • Yep for those that don’t know
      SAM exploit has been killed off by Apple….and I seriously missed it by like 4 hours…..*&^%&*!&*

  10. Does this R- Sim card still works?, even when Apple fixed the Sam thing? or does this card also uses the sam method?
