    I have jailbroken my iphone 3g 3.0 baseband 04.26.08, when I go to cydia and try to install ultrasnow using repo666.ultrasn0w.com, it states did not find repository. Should my sim card be in the phone during this process ? I also have a turbo sim, should this be installed ? I am using vista. Please help….

  • ANTIRebelSIMCard says:

    Dear users,

    The solution here REALLY WORKS, follow the steps shown here, I had a iPhone 3G, 2.2.1 BB 2.30.03 that I tried to unlock using the REBEL SIM Card, none of its current version worked for me besides this is a ALERT FOR ALL IPHONE USERS IN THE NET, they are selling this Software solution as it was from their authority,cheating people and taking advantage of what the DevTeam developed and who deserve donations for their effort.


    I upgrade my iPhone to OS 3.0 and followed the steps carefully and now my iphone works with this OS , Cydia and all its functions are working really well.

    Be patient and try one more time without missing any steps.

  • Jasmyne says:

    I am unable to download ultrasn0w. I keep getting “size mismatch” error in cydia. I’ve been trying for 7 days now. I have re-jailbroken, re-added cydia & re-added the repo several times. Always the same message. Icy adds the repo but does not find the app. Firmware is 3.0 on 3g phone. Can anyone help me please? Thank you.

  • minh says:

    to answer your question for Cydia “did not find repository”. That was because the ultrasn0w.com website was down temporarily. With a little bit of patience you should open a browser, enter repo666.ultrasn0w.com and check to see if it is up again. Then at that moment, go to your Cydia, add source, and it should work

  • Get says:

    To those who got message “did not find repository,” I had the same problem and tried several ways to fix this. Finally, I found the solution that worked for me. What you have to do is just update your Cydia ( Full update ). First,I just update only essential component and had problem when trying to add source “repo666.ultrasn0w.com” or “repo666.ultrasn0w.com/”( with “/”). Hope this help !

  • liver says:

    I’m having the same problem, I don’t know whether it is because my o2 sim hasn’t been activated, I live in a place with no o2 coverage, or what. Did you do a restart after installing the updates?I did install all updates but it still didn’t work I’m wondering if I had to reset the phone.


  • mayank says:

    Hi, I went through with the jailbreak process, everything went perfectly but on the home screen i cannot see the cydia icon, its just not there, what do i do about this?

  • V1123 says:

    When I try to add “repo666.ultrasn0w.com” it says “Did not Find Respository”, how do I fix this problem?

  • Minjaben says:

    Hello, I used the ultrasn0w for unlocking my 3G 3.0 Iphone and it worked perfectly. The only problem I have is that I cant syncronize with my old Itunes Account. I got to syncronize the half of the library the first time I plugged, but now every time I plug It, says the “disk was not found” or “server time out”. Can anyone help me with this.


  • Azad says:

  • John says:

    @ step 3 is just wrong – it should be go to SOURCES not PACKAGES.
    I have huge problem, just cannot get ultrasn0w to load, is there any other way to run it?

  • flyingthunder says:

    itried to manythings to unlock via icy or cydia through repo666 but no chance to unlock the iphone any help pleaseeeeeeeeeee

  • dome says:

    K 1st
    you must be near a Wi-Fi A.P.(access point)

    can u start referring the 2/3G as 2/3Gen as the n00bs may
    think ur talking about 2G(GSM) or 3G(usim)

    and John if you read the insturctions it says “Dont install Both Cydia and Icy”

    and azad
    u need to wait till dev team can exploit 3.1 software
    unless u own a Macintosh u get “Pwnage tool 3.1”

  • John says:

    @ DOME, yes, I understand that one should not install both Cydia & Icy at the same time; however, I am sure that upon finding that one program would not work, even you would try the alternate, what else to do to solve the problem. At any rate, the problem was not with either program, I believe the Cydia site itself was at fault or my access to it; here is what I posted on another site –

    @ Jordan,
    Don’t give up – I had this exact same problem for a week or more. My iPhone (3G, 3.0, from Australia) was able to surf with Safari, however Stocks & Weather would not update, even when right next to the wireless antenna.
    I am not sure sure how these two problems are related, but I do know that one day, Stocks & Weather did update, and Cydia ran, updated itself, then I did the ultrasn0w and it worked without a hitch.
    As I am in Saudi Arabia and it was a work modem, at first I thought it was a proxy problem, but as it eventually accessed via that system, proves that theory wrong.
    Is there any way there could be an internet glitch between here and the Cydia website and the same for you? Or perhaps Cydia site was down but that doesn’t explain the Stocks & Weather not updating.

    @ five00seven,
    Thanks for trying to help, I am fully aware of the idiosyncrasies of working with Wi-Fi in conjunction with firewalled internet access. I had the company proxy settings in iPhone settings, and entered the User Name and Password every single time after opening Cydia.
    The time that it finally worked, I did nothing different than before; hence, my question about an access problem to the website or even an internet blockage between here and there. Be interesting to see a follow up from Jordan, did he finally solve the problem?
    I did get a lot of proxy errors when Cydia failed to access properly, but they were not related to my company proxy, more like they said Proxy 407 or something to that effect. The time it finally got thru, it was a beautiful thing to watch, I just knew that it was going to work, you could tell by the way the files were downloading.

  • Rob says:

    Could someone send me the ultrasnow program all this cloak & dagger is realy tiresome.

  • Pulkit Manghani says:

    and yes i turned off the 3g network befor installing it.
    can you please help me? i’ve looked all over the web for an answer but none seems to help.


  • Chou says:

    I am experiencing the sme problems as the two posts before. Searching then no service. It worked the first few days perfectly but then tells me a restore is needed and I cannot make or receive calls. I have been searching the net for two days. Sometimes u can reboot and I get service but then randomly I will lose it and have restored rejailbreak and reunlocked several times using Cydia and ultrasnow. I don’t know what’s going on but someone plz help. Yes I already tried turning 3g off before installing my tmobile sim card. I’m about ready to give up.

  • NEED HELP says:

    I Jailbreaked my iPhone then there wasn’t service (before i jailbreaked it the sim card worked) then i unlocked it, now it keep saying Searching…

    Help me please.

  • chou says:

    alright guys…i finally got my phone fixed. i was the one who posted two posts ago. long story short…my 3g 3.0 got the point where it wouldnt even restore. kept giving me an error (1013 or something like that. i left it alone for a few days and tried it on another computer. it finally restored! we jailbroke it using redsn0w but for some reason the wifi settings was greyed out and said “no wifi”. after restoring it another 2 times (we got the error again) we still got no wifi. my friend then read a crazy post saying to put your iphone in the freezer, we tried it and it worked! so any of you experiencing that, turn your phone off and put it in there for a couple of minutes. so we got it unlocked and after a few hours the dreaded no service thing popped up. so we tried to reset network settings (settings>general>reset>reset network settings) and it came back. when it happened again my friend did the freezer thing and it worked then we heard from a friend to go into settings>carrier and PICK your carrier. it is defaulted on automatic….but the choices under that for me was tmobile and at&t. since im tmobile i chose that instead of automatic and so far it has been working fine…but its only been about a day. i just wanted to share this with you guys if you were still looking for a solution. good luck to you guys…im crossing my fingers and hope my phone holds up. oh yeah but now itunes is saying it can’t read my phone and i need to restore it so i’m unable to sync it. if anyone has a solution plz help, i do not want to restore it again bc im afraid it wont work again. but im sort of fine with it since my iphone atleast works now.
