  • Warning: ultrasn0w May Break GPS on Baseband 6.15.00


    The Dev-Team is warning about a potential issue with ultrasn0w for iOS 4.2.1 on iPhones with the 06.15.00 baseband. An increasing number of users with that version of the baseband software are reportedly losing GPS functionality when they unlock their device. The blog post says they are looking for the root cause but haven't found it yet, and notes that it's not a problem for all or even most users with that baseband. Still, to be on the safe side, they're suggesting people should just not expect GPS to work if they want to unlock iPhones with the 06.15.00 baseband using ultrasn0w:

    Update #5: Unlockers have been reporting mixed results about GPS functionality at 06.15.00. Until we can track down what differentiates those who retain GPS vs. those who lose it, be conservative and assume you’ll lose GPS at 06.15.00. As we work on finding the cause (and possibly a fix), please report your personal findings in our comments section. (Update: early indications are that while 06.15.00 is capable of GPS, it will require some further hacks. But please still be conservative and assume you will lose GPS at 06.15, in case the hacks don’t work).

      I can confirm that 4.2.1 3g 06.15.00 has gps problems. When using maps the current location is 3 blocks off.

      Well I'm guessing Apple knows what's going on and in 4.3 they will include a baseband update to 6.16.00 to break ipads baseband hack

      We should never give up hope just enjoy the lovely work which you didnt have to pay for and go on you merry way ha ha
      There will be no downgrade except for the very small percentage of 3G phones with 5.08 boot loader. 98% of people will be stuck with this baseband, most likely forever.

      They warned people. All they did was come up with an option to unlock iPhones stuck at an unlockable base band. People didn't have to do it. I think to have a iPHONE that can make PHONE calls is more important then having gps. If you used this method to unlock your iPhone and you are mad because gps doesn't work, tuff **** the dev team said there was risk so live with it or get a new iPhone and use it on a supported carrier.

That alone was enough for me to what it out, especially since 4.2 isn't much of an improvement over 4.1.
      calculated RISKS are still risks.....period. PS. the economies growth came from risk as well. all pos AND neg in life come from risks in regards to the unknown & change.

      So really what is the risk? Going without GPS for a while until they find a fix? Doesn't seem like that huge a loss to me. If people didn't take risks we wouldn't have half of the things we have today. The fact that people had issues in the first place has opened the devs eyes to the problem existing at all.

      exactly, i agree...no one said do it. we (rather those who did) CHOSE to do it. wasnt really a risk. more like a weighing of priorities..GPS? or PHONE CALLS

      What saunupe1911 was saying is that people should take smart risks, and informed ones. For people that don't use GPS or don't really need it, no great loss. For people that *do* rely on it.... problem.

      The risk was the same for everyone: small chance of brick, small chance of unknown hardware misfeatures, good chance of no problems. But the impact and implications aren't the same for everyone, and the people who are most severely affected by this problem possibly should have considered and weighed the risks more carefully before jumping in.

      Idjits who blindly rush out and update to the latest FW from Apple every time, and immediately beg for a JB and can't understand why they weren't warned not to upgrade (they were warned) are the ones who tend to get burned. They do little or no cost/benefit analysis, and sometimes they get lucky and sometimes not.

      People who generally understand the risks, and dive in acknowledging and accepting them (I imagine, people like you) are the kind of risk-takers that benefit the world. The ones who don't understand but dive in anyway are cannon fodder. Their major benefit is becoming fertilizer

      This problem is specifically for "unlocking" and not "jailbreaking" correct?

      @raduga,

      Very intelligent post, especially the last paragraph.

      @cougamvp1
      Correct. The problem exist for those who upgrade their BB to 6.15 in order to turn their iphone into a phone again rather than ipod touch.

      This wasn't a jailbreak, it was an unlock. There is a difference. And what Firmware (4.1 or 4.2 that you chose not to upgrade to) you have is not the same thing as your Baseband. I didn't upgrade my to 4.2.1 Firmware (I stayed at 4.1), but I did flash my Baseband to 06.15.00 in order to unlock my iPhone 3Gs to work on my carrier of choice. I was aware of the risks when I did it and read everything I could read about it thoroughly before going ahead with the Baseband upgrade, and am not sorry I did. My GPS also puts my location off by a few blocks, but if that is the price I pay in order to have an iPhone that works in every other way, I am good with that. Greatful, even. The Dev-Team does a great job delivering us with the ability to use our iPhones how we want, but even developing geniuses are imperfect humans and they can't predict all of these problems all of the time. They provide us with the options and we make the choice. Those of us who educate ourselves of all the facts and weigh the risks and benefits before making the choice don't often regret our choices.
