Hi, I have same question like following one still@firmware 3.0 wrote at 2009-11-10 19:03:59 I have a 3GS with version 3.0 still on it - but it is unlocked and jailbroken and has cydia installed. I did not upgrade to 3.1.2 because I am afraid of it becoming locked, or bricked. I try to install blackra1n through cydia, but after I click \"install\", I get this message: \"Note: the requested modifications cannot be applied due to required dependencies or conflicts that cannot be automatically found or fixed\"... and then it dos not let me install... I believe I need to upgrade to 3.1, but I\'m afraid that if I do that, I will have to reinstall Cydia or not be able to unlock it again....has this happened to anyone or does anybody know what I should do? I don\'t really get the certain answer. How do I upgrade to 3.1 before I use blackra1n tool to upgrade to 3.1.2. Because I\'m already jailbroken and unlocked with 3.0.1 version, should I use any tool to upgrade to 3.1 or just upgrade officially from itune?? Please HELP ME!! Much appreciate!!

Hi Justin, Re update your phone again, it should work with no problem, re do all the steps again, it seems there is something causing this reboot which will hopefully be solved after you reupdate it.

using bootloader has worked for a lot of people, but not for me. you might want to try it: http://www.redmondpie.com/jailbreak-unlock-iphone-2g-3.1.2-firmware-with-blackra1n-rc3-9140086/ let me know if you managed to get this to work, or if you find some other way. i\'m still in limbo. when i get some time i\'m going to try downloading the firmware and trying a different approach.

I'm not having experience with Blacksnow . To unlock your iPhone 3g, use Remote unlocking method . You can get it from any of the online vendors like ProUnlocking.com to unlock it .

PLEASE HELP

have 3GS (32GB) that came with v3.1.2 (05.11.07) and carrier-locked. Used blackra1n/blacksn0w flawlessly however when I insert preferred carrier SIM, the phone recognises network/carrier but no signal. When attempting to call that number, I get a std message saying ‘the number you are calling is currently not available….’ hence cannot call/SMS nor receive calls/SMS. I’ve tried doing ‘full network reset’; ran blacksn0w again; completely wiped and performed factory restore….no errors…but the same problem exists… Anything I\'m doing wrong??? any suggestions would be much appreciated.

My friend I think this has nothing to do with blackra1n, can you try any other sim card and see, if the problem still there I think you must have your iPhone checked and serviced.

I\'m experiencing the same problem on a 2G iPhone after installing blackra1n and blacksnow. i now effectively have an iTouch, instead of an iPhone. the SIM definitely works, since i\'ve tried it in another iPhone (unlocked 3G). \"Cellular Data Network\" doesn\'t even show up in Settings/General/Network. Signal bars show zero reception, and eventially \'No Signal\' replaces it. however, the iphone next to it has full reception. i don\'t know if carrier or location is involved in this, but I\'m in South Africa using Vodacom.

Ashraf...yup...did try UL/JB using 2 different carriers SIM...same story :( I\'ve no doubt on blackra1n/blacksn0w effectiveness. I think my \'brick\' is most probably IMEI locked. May work if I tried with overseas carrier SIM. Will update if it works that way. Yudha...are u using Indo SIM on Aussie handset? because in past I\'ve used Dev-team JB/UL solution on 3G (on 04.xx BB) and it has worked w/out any hitches whilst using various SIM in Oz. If your BB has been upgraded, just d/grade it and try. Callan....mate..although I also use 2G but haven\'t tried Geohot\'s release on it. Quite happy with v3.0 on BB 04.05.xx. I think you should perform factory restore; check BL and take it back to pre-upgrade state, try removing/inserting SIM; switch airplane mode on, wait 30 secs, turn off and see how it goes. I think 2G JB/UL can be quite comfortably manipulated

My friend I think what ever you do will not harm your iPhone, I myself spent 1 week doing upgrades and downgrades using many utilities, the good thing is that you can always do a restore using iTunes, do\'nt be afraid of trying. At the end the best and the fastest way of having your piece Jailbraked and Unlocked is using blackra1n, just follow the steps which are available here at iclarified.

Possible solution to GPS, WiFi, Youtube problems. What I did is, I put my original O2 SIM card and restored my iPhone 3GS with iTunes to factory settings. Then I jailbreaked wih BlackRa1n (still with O2 SIM) and unlocked with BlackSn0w. i checked to see if all is working - YES. After that i just replaced the SIM with \"unsupported\" SIM that I use. All is working: WiFi, GPS and Youtube without any problem. Hope this helps.
