Actually, I can't figure out which it is. It's got the pic of Steve Jobs speaking Russian. I've tried recboot and a few other apps, and I've made no progress. I'd do a full restore from iTunes and not worry about the jailbreak, but this is my brother's iPhone, and he's actually on T-Mobile... so I need the unlock to work. I'd prefer to just magically get this thing out of whatever mode it's in, rather than have to create a new firmware bundle or anything like that, but I'm open to whatever. Curious to hear thoughts. Thanks!
 
I'm having similar troubles,

I've gotten it out of recovery mode, and into firmware 4.1 by trying this:

Dear Brothers & Sisters,

After some trial and error, I have managed to solve this problem, it may sound a bit ridiculous, instead of restoring to custom 4.2.1, I have restored it to 4.1 stock firmware (iPhone1,2_4.1_8B117_Restore.ipsw) and after the restore, you will still get 1015 error, but miraculously the recovery mode logo has changed if you observe properly, just ignore the error and use either recboot or iREB-4.0.x-4.1-RC2 to kick the phone out of recovery mode, the restoring bar will start again and wait until finish, you will get an Iphone with firmware 4.1 and baseband 6.15, use redsn0w to jailbreak and ultrasn0w to unlock. I have solved my Iphone 3G with this method, other models have not been tested, use this method on your own risk, hope can help those in deep misery now. Enjoy


Sincerely,

Pangio

But that's as far as I've gotten, the thing still isn't unlocked.
 
Okay yeah I can't risk going back to that baseband as he needs the unlock (he's just using an old beater phone for now). I think the best bet might be to wait for comex's untethered jailbreak to come soon. I'm hoping / thinking that with that jailbreak, we'll be able to preserve the baseband on the 3G.

Ok, perhaps I'm misunderstanding something... aren't all JB's on the 3G untheatherd?

Yes, the jailbreak on 3G iPhone are untethered.

"iPhone Dev Team:

Update #2: The notion of a “tethered” jailbreak is pretty new to many people, so here’s a quick rundown on what to expect:

If you’re on an iPhone3G, old-bootrom iPhone3GS, or non-MC ipt2g, life is easy. redsn0w installed an untethered jailbreak and so nothing below applies."

If I was the iPhone owner, I would prefer that my baseband be on 04.26.08 or 05.11.07 or 05.12.01 or 05.13.04 to retain easy unlockability. In other words, anything but 05.14 or 05.15 (which closed the hole) or that iPad-borrowed 06.15.00 (GPS-futzing). 4.0.2 is the highest stock IPSW with one of these easily unlockable basebands (05.13.04).

Before going further, I should ask questions. I'm guessing you jailbroke it via RedSn0w. Am I right? Are you using Mac or PC?
 
...With the above, the direction I was heading in was..to suggest you try to use Pwnage Tool to force it in to DFU mode. But that's only an option if you are on a Mac.

While browsing Big Boss website, I came across this for those stuck in recovery:

Just to close this thread. Here's what I did. I plugged the iPhone 3G back into his computer. I restored it to the newest firmware, and then I used redsn0w to jailbreak it and load the iPad baseband onto it. Then I downloaded ultrasn0w. The phone is back alive and unlocked, happily on t-mobile, running the newest iPhone firmware. So that's good. GPS is not quite functional with this iPad baseband, but I think it might get fixed. Either way, not a huge issue. He's going to buy an iPhone4 for Christmas anyways. This will last til then.
