Sounds like it. Would be nice to know if any one else has an MB489LA and is getting "no service". Wish I knew more about these things and could really get in there and figure out what the issue was! Sorry you're having trouble, voyage! I was lucky enough yesterday to find a coworker with the exact same type of 3G I had, but that was the MB702LL variety, and we traded phones. So NOW i finally have a successful unlock after 10 months of not being able to use a phone. But I'm committed to seeing this issue through!

I think it's safe to say I get a little "long winded" sometimes. Hahaha. I apologize!! Wed, 30 Jun 2010 13:53:21 +0000 http://blog.iphone-dev.org/post/726179754#IDComment83466572 http://blog.iphone-dev.org/post/726179754#IDComment83464598 OK, I've got a theory about the "no service" issue I and a lot of folks are having after we unlock. And I need some of the more knowledgeable folks to chime in if they know anything about this: I bought a 3G from a friend of mine back in August of last year. It had already been updated to 3.1.2 at the time, so I had no way of jailbreaking and unlocking. So it sat in my bedroom while I continued to use my 2g. Then in October when geohot released blackra1n and blacksn0w, I got super excited and immediately went to work on my 3G. Only to be super disappointed when after 10 different restores using every possible method of restoration/jailbreaking/unlocking, getting a new SIM card from T-Mobile, trying every damn thing that ANYBODY suggested at that point, I had a bizarre issue, which I thought I was the only one until gradually others started cropping up on this blog having the same exact issue, where when I would unlock, it would take my T-Mobile (US) SIM, and all, and would have a few bars of service, and then gradually go down to no bars, and then No Service. And I could never get service hardly. Unless I rebooted my phone, then it'd give me 1 bar for a few seconds, maybe a minute, then back to no service. Well, after a month of all these attempts, I finally decided that it must have been some sort of bug in the way blacksn0w did it's unlock, and i put the 3G back on the shelf in my bedroom, and continued using the 2g. Until a week ago, when the dev team announced the new version of redsn0w and ultrasn0w, and I got super excited, thinking that if blacksn0w had a bug in the unlock, surely the Dev Team's software wouldn't. And to my great disappointment the same exact thing happened. No service. Period. Ever. Tried everything. NOTHING worked. Until yesterday. I borrowed a coworker's iPhone 3G that was identical to mine as far as storage space and color and all that. And I made a backup of her phone and then jailbroke it, and unlocked it, and it worked like a champion! So I started poking around and noticed something: under Settings -> General -> About, my 3G was a model "MB046LL". And her 3G was model "MB702LL" So I got on here and asked one of my fellow non-unlockable friends what his model was and his is an MB048LL. I've got another co-worker who just got an iPhone 3G with the model MB702LL, and his also unlocked just like it should with no problems whatsoever. SO, my big question for you guys: What I once decided must have been a bug in the software used in blacksn0w and ultrasn0w, I'm now thinking it has nothing to do with that, but rather some sort of big difference between the 3G model MB04*LL and the other 3G models. Can anyone tell me what the differences are between those? Also, I'd love to hear the model numbers of anyone else using a 3G having the "no service" issue. Thanks you guys! And thanks SO much to all the Dev Team for all the incredible amount of work they do for us. And another big THANK YOU to all of the super-knowledgeable people who lend their brains to us in these comments. We wouldn't be here without you! **Raises glass to the iPhone jailbreak family!** :-) Wed, 30 Jun 2010 13:36:45 +0000 http://blog.iphone-dev.org/post/726179754#IDComment83464598 http://blog.iphone-dev.org/post/726179754#IDComment83461854 Ok, I think I know what the problem is. Your model is MB048LL. My 3G is MB046LL. Neither work with the unlock at all. However, I switched phones with someone yesterday who had an identical 3G as mine, 8 GB, black back, etc, but her model is MB702LL, and it unlocked like a champion. I'm using it as we speak. No problems whatsoever. I have no idea what the differences in these models are, but what I had been chalking up as a bug in the software, I'm now thinking is simply that on these MB04*LL models, something in there is very different. I'd be quite curious to know. Hopefully someone can chime in who knows more about the internals in these different "models". My advice for the time being, find somebody who can switch with you if at all possible. One of my coworkers had a 3G and just used it on AT&T, no jailbraking or unlocking, and her's looked identical to mine and had the same amount of storage and all that jazz. So I asked her if I could borrow it to run some tests on it, and I backed all her stuff up and then jailbroke it and unlocked it and it worked great, and so I restored all her backup and everything to MY 3G, and then explained the situation to her, and asked if she'd mind switching phones with me. And once i showed her her stuff on my phone (which looked identical except waaaay cleaner than her phone ;-) then she was totally cool with switching. I told her if she had any problems with it, we could easily switch back. I don't know if that's even a remotely possible solution for you at this point, but honestly, until there's changes to the method ultrasn0w uses to unlock, i don't think there's any other way :-/ Wed, 30 Jun 2010 13:14:20 +0000 http://blog.iphone-dev.org/post/726179754#IDComment83461854 http://blog.iphone-dev.org/post/726179754#IDComment83219333 Hey David, if you go under Settings -> General -> About, scroll down and tell me what it has for Model. I'm curious to know what significance that might hold and if we might have the same models. Let me know! Thanks!

I LOVE YOU, DEV TEAM!! :-DDD Tue, 29 Jun 2010 15:01:45 +0000 http://blog.iphone-dev.org/post/726179754#IDComment83128771 http://blog.iphone-dev.org/post/726179754#IDComment83128028 David, sounds like you're having the same issue as quite of few of us on here. Did CON's suggestion to try the IPSW from the iCommunity site help at all? Please keep us updated! We feel your pain!! :-) Tue, 29 Jun 2010 14:55:49 +0000 http://blog.iphone-dev.org/post/726179754#IDComment83128028 http://blog.iphone-dev.org/post/726179754#IDComment82788195 Hmm, that's odd. I see it once I install ultrasn0w. Doesn't really matter for me though, since I don't get any service to begin with! :-/ I'm assuming you're unlocking with ultrasn0w 0.93?

I don't know what else to try. :-/ Thanks for the suggestion though!

We've yet to find any possibly fix for it. Check my past posts for details. Spread the word!! Hahaha ;-) Mon, 28 Jun 2010 18:06:54 +0000 http://blog.iphone-dev.org/post/726179754#IDComment82787113 http://blog.iphone-dev.org/post/726179754#IDComment82787033 Hey jcth, yeah, i've tried evvvvverything. Click my username and see my past posts to get an idea of all the crap i've already tried. Haha. Thanks for the reply, though! :-) Mon, 28 Jun 2010 18:06:12 +0000 http://blog.iphone-dev.org/post/726179754#IDComment82787033 http://blog.iphone-dev.org/post/726179754#IDComment82782261 Can I send my 3G to you guys at the Dev Team so y'all can have a phone to test this "No Service" issue with?? I'll donate it for the cause if that's what I need to do. I'd love to get it back, haha, but at this point, i'd be willing to donate it for the greater good!

All of my attempts have been referring to the 3G that I have. I do NOT have a 3GS. That is my friend nemishnandy that has the 3GS. And he's trying to get it working on 3.1.3 I'm trying to get my 3G working on 4.0 I haven't been able to using ultrasn0w, and I wasn't able to get it working on 3.1.2 using blacksn0w either. :-/ Mon, 28 Jun 2010 17:24:44 +0000 http://blog.iphone-dev.org/post/726179754#IDComment82782044 http://blog.iphone-dev.org/post/726179754#IDComment82781575 According to CONVBMW, he thinks it's a bug in the unlock process ultrasn0w uses. That's the only conclusion I can reach as well. I suppose we'll just have to wait and see if a fix comes out at all. :-/ Mon, 28 Jun 2010 17:20:43 +0000 http://blog.iphone-dev.org/post/726179754#IDComment82781575 http://blog.iphone-dev.org/post/726179754#IDComment82775177 Ok. Tried that. No dice. :-/ Thanks for the suggestion though!! Mon, 28 Jun 2010 16:42:49 +0000 http://blog.iphone-dev.org/post/726179754#IDComment82775177 http://blog.iphone-dev.org/post/726179754#IDComment82770971 That's a thought. I haven't tried that. Not holding my breath, but I'll go do that real quick! Mon, 28 Jun 2010 16:27:47 +0000 http://blog.iphone-dev.org/post/726179754#IDComment82770971 http://blog.iphone-dev.org/post/726179754#IDComment82770808 Hahaha yes, indeed. Comprende! Unfortunately, I've already tried that and it doesn't work for me. :-/ But thank you! Mon, 28 Jun 2010 16:27:11 +0000 http://blog.iphone-dev.org/post/726179754#IDComment82770808 http://blog.iphone-dev.org/post/726179754#IDComment82768351 Thanks so much, CON. Honestly, it's nice to have someone else pawn it off to a bug. :-) I've been thinking that for quite a while now, but it seems everyone around is saying "No, it's not a bug, you just haven't tried everything." And I was thinking that it was a bug with blacksn0w, which was when i first started experiencing this issue, and i was excited to try ultrasn0w. But I guess they must use the same method. :-/ Thanks for affirming that at least I'm not crazy. :-D Hope your day is great!
