    I want to belive that this new is through!

    Dear unlockboot, can you please reply to me as i want to know if this R-SIM 4 will be aviable also in European countiries such as :Albania, Kosova or Macedonia?

  • Dvijenec

    UPDATE April 5th

    Apparently it is not easy to unlock iphone 4 baseband 4.11.08, but at this time we have at least 50% to unlock the iphone 4, so we still need 1 week more or less to improve the program, and please stop sending email to us, just add our facebook page or twitter or keep an eye on our site, we will update the info once it is available,

    Also it is not a April joker.

  • Bebo014cf

    will this work for 04.12.01??

  • Gal Naim

    will it also unlock at&t phones ?

  • Sizzler

    “Apparently it is not easy to unlock iphone 4 baseband 4.11.08, but at this time we have at least 50% to unlock the iphone 4, so we still need 1 week more or less to improve the program, and please stop sending email to us, just add our facebook page or twitter or keep an eye on our site, we will update the info once it is available”

    I smell BS. Why would they post a purchase page on their website and already come up with a price before even testing the product works…
    Don’t be surprised if this turns out to be fake like Gevey taking months, even years to unlock a lousy baseband.
    BTW My carrier is KT Olleh, I’ve been told that I can get it unlocked for free but I’m not Korean or have an account with them, If anyone wants to help me out, let me know please, Thanks and Good Luck all

  • Zaxos_42

    I think the best way to sell this R-sim worldwide is ebay . Because i live in Greece and i want it and many people who live worlwide (expect U.S.A) want this card too . And ebay has and secure, good for you and good for us .

  • oat

    Permanent unlock is exit. My i4 model mc605ks from Telia Sweden has been unlocked couple days ago. At&t unlock have to wait 2-3 weeks for this unlock service on at&t server will be available.

  • Nick Knock

    i think no one at this time can unlock 4.11.08 bb 

  • JI

    Hey I’m Korean who lives in US. I think you can get it unlocked for free when u visit KT main service center(not the small stores, but the main one ! ) if you have a contract with KT or a member. I still need to know ur accurate situation( like green card or ur contract blablabla) but I think KT service center will explain you in detail. I hope you get it done easily ! 🙂 good luck

  • Lustful
