    Default [*Sim] [3G] Results from data observation - Stay away from *sim solutions.

    Hi guys,

    First of all I want to thank everybody who sent me their logs so I could see if the *sim solutions were using different methods.

    Though it may sound a little frustrating to some of you who believe this would work out if we could find a tweak to the methods implemented by the 'almost-there' solutions.

    By collecting all the data and checking the logs to see how each sim dealt with the IMSI information (something like your ID on the network) I could compare legit, legit with *sim, locked sim + *sim.

    My conclusion is as follows:

    All of the tested solutions use IMSI solutions that are not appropriate and could possibly get you in deep trouble.

    Here's a little explanation of why it worked before and why it's not working anymore (and possibly will not work ever)

    People found out that the iPhone asked for your IMSI twice, the first time used to be for the iPHone itself, and the second time was relayed to the network for identification. What they did was they created a program that would respond to the first request with a IMSI that belonged to ATT network so that the iPHONe would believe it was working with an ATT sim card, but to the second request the program would reply with your own IMSI and this would be sent to the network which would make your proper identification in the network.

    What changed?

    Apple got smart and changed how this works. Now the requests aren't so simple and so far it seems to us that it's not possible to fake the IMSI using the same techniques that were used before.

    An example of what could be happening:

    the iPhone asks your SIM for it's IMSI and then relays that same IMSI everytime it's needed by the network without consulting your SIM again and again.

    This way if we give the iPhone a fake IMSI, it'll relay the fake IMSI to the network which won't work as a stable, safe and legit (as far as networking goes) way.

    What's my plan ?

    I don't plan on giving up just yet, I believe much has to be learned about the baseband before we can rule out the *sim solutions. I will keep working on this at the same pace I have been (one-two hours a day).

    The next thing on my plate now is to attempt reversing some of the baseband in search of IMSI related or pretty much any SIM related calls. If I succeed in doing that I plan on using that information to try and create a reliable and safe way of using *sim solutions.

    I would advise everyone who has one of these chips to stop using them. Even though you might think it's ok, it's not ok because pretty much what you are doing is using a fake ID at a store or a fake credit card.

    Also for those who're using ZeroG, it's doing basically the same thing, so stay away from ZeroG as well.

    Don't throw your turbo-sim or whatever other sim you have away. Keep it with you because if someday we can find a proper solution they might be useful.

    I'll keep looking at logs of other solutions to see if they are using the same stuff but until it's safe to use a solution for a daily basis I would recommend that you guys keep watching the forums until it's proven by reliable people that such solution would work properly.

    This is my two cents about this subject.

    Thanks for everyone who helped me.

    Thanks Deco, keep us all updated. :hack: ...Dumb question, at what stage will those outside the Dev Team be able to access baseband code and baseband firmware? I know, that's where all the action is. Where huge risk is as well...

    You actually can do this without being in the Dev Team (as I am not).

    What you need to do is get the IPSW file and decompress it, then you'll find the ramdisk.. then you get the ramdisk and decrypt it and you`ll be able to mount it. Then you mount it and find the .fls file.. once you are there you have to know about the secpack and memory map so you can find the baseband firmware and attempt to Reverse it by using some tool like IDA Pro.

    The knowledge for this is all on the internet (a lot of it is in www.theiphonewiki.com) and with the last part (reversing) there's a lot of info on the net as well.

    If I get anything useful I'll share.

    Have fun!

    Tnx for the efforts and for the reliable inforrmation deco!

    Anyway, I hate this process, I hate it is unstable, and even illegal..

    But for sure can see a smile in my face everytime it works.
    Until now is the only way I got my carrier signal and I was able to receive/send calls/sms even though it was for a short time. Temptation...

    Hi DECO,

    I do not understand why should we not use the * sim if it work on my 3G iphone, we used the same fake ID solution in 2G iphone without causing problems. The idea of * sim is to cheat iPhone that we are using the correct sim, right?

    I have tested on three * sim solutions, the GExxx sim, the STxxxxsim SE, the isxm, none of them work 100 % right. They will work fine in one 3G network, but no service at all under another 3G network etc.

    There are a few 3G network in Hong Kong.

    Test results:
    GExxx sim>>>>>>
    a) PCCW (3G) : No service. no service at all in3G nor 2G network.
    b) Hutchison 3G : no service at all in3G nor 2G network.
    c) People (2G only): working fine.
    d) CSL (3G): working fine. working on 3G & 2G network, but under 2G network has a stronger signal strength.

    Stxxxsim SE>>> slightly better, same result as GExxx sim, but can get network in Hutchison 3G. In Hutchison 3G, STxxxsim SE sometime can connected to the 2G network only (not 3G) because it show 3G(2G) on the iphone top left corner. Occasionally , it sometimes has no service at all after a signal drop.Even waiting for hours, switching on & off again did not work.

    isxm>>> work similar as GExxx sim. not so good in some network.

    So is the result operators dependent ? or sim dependent? or base station dependent?

    Furiousim>>> I tried to test it, but I damaged it when I tried to put it out to change another sim from the iphone. .I shall get a new one & test again.

    iPhone2,

    As I tried to explain in my previous post, the solution is relaying a test or fake IMSI to the network which could be very bad for you.

    Just put them on hold while we do research, don't throw them away.

    When we get more info we'll be able to explain better, I don't understand the process exactly but I'm working with some people and as soon as I can pinpoint exactly why it won't (doesn't) work you can be sure I'll post here.

    Have fun!

    Hi,

    Deco is right, there is not any sim solution (in market) at the moment for solving edge/3G problem in iphone 3G.

    All this started here from this team yessim who only know how to make spam advertisement for incomplete solution that was working in universal sim before iphone was released, and they assume this for yessim.

    But i can not resist to tell you, there is sim solution (not in market, yet).
    I have ready universal sim new update for this.
    And is not based on IMSI, so i assume there is no more illegal involved here.

    Later we will post video for show you this.

    @deco: i wait you send me pm with details for sending you samples of universal sim, same like we sent already for other 2 members of this forum.

    @iphone2, are you based in Hong Kong? i can make for you live demo

    BR,
    Manole

    Meh. You started well, let's try to continue better post technical details than a video, or be ready for the template
