  • Yashua says:

    I tested redsn0w with iphone firmware 4.0
    on the iPhone 3G and 3GS

    1. IPhone 3G (firmware 4.0)
    iPhone 3G WORKS with redsn0w and unlocks / jailbreaks great.
    I even loaded Tethering that works from http://MMS.ifind2.com

    2. iPhone 3GS (firmware 4.0)
    DOES NOT WORK. Redsn0w cannot recognize the IPSW file.

    I got my iPad for $39 bucks at BidsWOW.com guys. This is for real.

  • sanki says:

  • Satya Nooker says:

    I was trying to jailbreak through redsn0w, the prcoess kept me waiting for long time at ‘waiting for reboot’ no sign of completion. Actually I updated my iphone 3g to OS4 through itunes automatically not through manual as I cannot find the ‘update’ button to select iPhone1,2_4.0_8A293_Restore.ipsw.

  • Hameed says:

    I’m using the other version of redsn0w; redsn0w_win_0.9.5b5-4 as suggested earlier and just like ‘M’ I haven’t had any luck at all, I cannot use my phone at all cus it doesn’t support my SIM card, please help as soon as possible !

  • Christy says:

    Thank you SO much! I had trouble getting redsnow to work after updating my 3G to OS 4.0 so I went back to OS3.0 and used redsn0w 9.2 with baseband 05.13.04 and it worked.

  • Saeed Ahmed says:

    i have an iPhone 3G 16GB, to update it to OS 4.0 and jailbreak i used (redsn0w_win_0.9.5b5-5) and successfully uploaded (iPhone1,2_4.0_8A293_Restore.ipsw)to with phone and it displayed downloading jailbreak data. After few minutes it restarted but still the phone is not jailbreaked as it still displays emergency call screen only.

    Any ideas wht went wrong, though i got no errors and things went smooth unless when it reboot it still shows the same old emergency call screen :(

  • Rookie8155 says:

    I tried to upgrade my jailbreak from firmware 3.1.2 to version 4.0 on my iphone 3G. I used Redsn0w 0.9.5beta.
    I downloaed ispw file for iphone 3g with firmware 4.0. Tried to jailbreak it. Everything seemed worked. After iphone re-boot, when I checked my phone, it was still on firmware 3.1.2.
    Please advise.

  • Ion Nedelus says:

    Sorry , but I have a big issue
    Every step from jailbreak with Redsn0w 0.9.5b5-5 seems to work properly , the iphone is re-booting after finalize , Cydia icon is displayed , only that my icon for Phone is disappearing (so I can not dial even I have Orange 3G signal bar, and the IPhone is ringing ) , and also internet connection is not working (not WiFi neither 3G), even the screen shows that the connection exists (Wi Fi or 3G bars are displayed , and the round sign shows intention for connection , but not really data transfer).
    So I could not go ahead , being impossible to update Cydia
    Have someone else got same issue? Where the mistake is.
    I double checked out – IOS4.0 is the correct one , Iphone is 3G , Model MB
