iPhone 3G Unlock Updated: yellowsn0w hits 0.9.5

The iPhone Dev Team is still hard at work on their beta, pre-release version of the yellowsn0w process which runs on Jailbroken iPhone 3G's to unlock the devices from their carriers. The latest, 0.9.5 is working for some folks right now, but others are still experiencing problems including the inability to make outgoing calls (signal drops off). If you're trying and failing, be sure to give the Dev Team your feedback.

In addition, the Dev Team is also girding themselves, and their code, to fend off those who violate the yellowsn0w (and pwnage) license and try to make a buck by re-selling the Dev Team's work to unsuspecting web surfers. Whether you can really go after someone for abusing the license on a unlocking process that is designed to let people abuse the license of locked products shows just how complicated both commercial and non-commercial protectionism and freedom movements have become.

If you're unlocked, or trying to unlock, let us know how it's going for you. If you have any opinions on the debate around freeing commercial hardware and commercializing free software, drop us a comment as well!

  • Iam happy if it worked for sum but hasnt worked at all for me singnal goes from full to zero and seraching for signal and every version has done this and cant believe none of the dev team had any problems like this because a ton of people i know couldnt make out going calls i just cant believe this didnt happen to dev team
  • No pity. Live by the sword, die by the sword.
  • Agree with previous comment. If you dick about with this stuff and it doesn't work then you can't blame anyone but yourself. I bought a jailbroken 2G and happily hacked around with of bit once I went 3G on a contract I decided to leave it be after an unsuccessful jailbreak that bricked the phone. Never again!
  • I'm having problems with 2 iPhone 3g and everytime i jailbreak n unlock them they work with the sim it came with but when I switch the sim cards 2 put T-mobile I get the different sim detected error n please connect to iTunes
    But when I do I can't do anythig else
    I have rejailbreak n unlocked with different option but no fix......can anyone help??
    Even if I put phone A sim in phone B I still get the error..really weird.
    2days before I unlocked another iPhone 3g n worked fine
  • Forgot to say that T-mobile shows up n I can recieve caps n text by can't do anything else cuz I keep getteing the different sim error n won let me go in re menu at all
  • Well to tell u the truth devteam screwed many people over. People who once had version 2.1 on their iphones were using turbosims which worked without a problem. Now these smart idiots who told us to upgrade to 2.2 realized their beta software is garbage, and we suffer in return because 2.2 cannot be unlocked with almost no turbo sims. They should have warned us from the beginning that problems will arise and that this is not done yet. They made it seem as if christmas eve would be the day to use iphone 3g without turbo sims. I can make a software up also and name it "blueballs" but if it doesnt work then wtf is the point ? right?
  • I had success with me and my wifes 3g's unlocked using their method. it works great. Just had to reboot and flick flight mode on/off once initially. Now it's flawless.
  • @ Michael from #6:
    a) You're and idiot, you used FREE BETA software at your own risk, and you were warned in the process!
    b) It probably works fine, but you're either too stupid or too stubborn to read and follow the instructions...
    @ rene:
    a) There is an exception in the law (DCMA) for unlocking your own cell phone
    b) Jody Sanders, at the ripoff site, is also selling a modified version of pwnage, which is legal software -- no apple packages -- that belongs to its creators; FULL. STOP.
    Install YellowSNow 0.9.5 Through Cydia
    Install BosPref with Cydia
    Install Mobile Terminal Witg Cydia
    You are done now, Put Everything OFF in Bosspref (SSH, 3G, EDGE, WIFI)

  • Hey Guys and Gals-
    First off thank you, thank you, thank you!! Freedom from our contracts are within reach. I am currently in California and with AT&T and want to move to T-Mobile. What sim package is recommended? Also will be moving to the UK in the fall, and going to get the iPhone O2 PayG sim card from ebay. Thanks you have saved this poor college student a fortune!!
    Rock on!! Cheers!
  • @Ravishan, that syntax "*0 <– # 0" does not make sense. Can you please verify what this is supposed to do? Obviously the Unix kernel of the phone will crap out on the # character ;)

  • I just bought a turbosim so I could use my iphone with my t-mobile sim, well I can now make calls but no internet??
    My phone isn't jailbroken or previously unlocked...what should i do?
  • I have unlocked my iPhone 3G. I have used a unlocking method from unlockiphoneuk.com and they sell that program for £19.99. Yes !!
    It did work fine, but the only problem i have, sometime when im using a pin unabled sim cards, it does not find the carrier. Once i put a pin dissabled (any network) it works fine, and it does not effect anything whatsoever.
  • @Nick, why pay for free, and freely licensed software? To the best of my knowledge, the unlock comes from the Dev Team, so why not just get it from them and save what's a pretty massive amount of money?
    It's like buying local tap water at the pub for $100?
  • Thanks for the info on cell phone unlocking. I love cellular phones and work at a little cell phone shop where we unlock phones and mod them for people. Add http://free-cell-phone-unlock.com to your list of free cell phone unlock sites, I use the downloads there a lot to help me unlock phones for customers, don't be mad but hey I have to make a living some kinda way!! lol.
    Anyways, I figured you could use that in your bag of tricks too :-)
