I recently bought an iPhone 3GS. It has model # MC***** and serial number 32949******
I took this to mean I had the new bootrom, which requires a tethered JB with B.Rain.
So tonight, I had to restart the phone. And it restarted without being tethered. I thought I had done something weird, so I did it again.
Hold down the button up top until the slide appears. Slide right. Watch spinning wheel. Screen goes black.
Start it back up by holding the top button again, and sure enough, back to running and I never hooked it up to the computer.
Did I not shut it down properly? Is there another way to do it?
Is there a chance I have the old boot rom even with a week 49er? Or what am I missing?
Yes, I am sure I am still jailbroke, I can see the X theme I have installed and I just got off Cydia.
I am going to sleep now, I will ponder this more in the morning!

Maybe it's a refurb.

So, what does this mean for me now, in terms of restoring if I should ever need to? I don't have 3.1.2 ecid/shsh on file @ cydia (they had stopped signing 3.1.2 before I got the phone). But with the old bootrom, can I restore to a custom 3.1.2 following any one of the many tutorials available if I should ever need to (knock on wood it will never be an issue)?
I am reading as many guides/tutorials/posts as fast as I can here!! I am not quite as efficient using the search function here yet

I'm assuming you're jailbroken on 3.1.2 now. The old bootrom does give you a little protection because if you ever get stuck and need to restore to get your phone working again, you can use a custom firmware made with either pwnagetool or sn0wbreeze (I personally recommend pwnagetool). This is something people with the new bootrom can't do because custom firmwares don't work for them.
You'll never be able to go to 3.1.2 again since you don't have the SHSH file for that version but you don't really need to either. You can simply restore to a custom firmware of the current version, which would be 3.1.3 if you were to do it now.

Yes, it tells me that you have a 16gb 3GS. I wanted to verify that you had the 3GS and not a 3G

I have a 3GS, MC model and week 44, jailbroken with blackra1n untethered. This serial number guide can't be all that accurate.

If it was a refurb the second digit should be a letter not a number.
It's not 100% accurate but it's a quick way to tell.
I don't think it's possible for apple to change their entire assembly line in one week.I always feel sorry for the guy in the iPhone commercials. He always gets a call right in the middle of trying to do something

We know that apple starte shipping the 3GS with the new bootrom in the 40th week. There are mixed bootroms in weeks 40-44. After week 44 almost every iPhone has the new bootrom with the exception of some refurbished devices

I am just going to count myself among the few and lucky! Week 49 refurb with old bootloader! Sometimes I just get lucky. Not often mind you, so I will take it when I can get it!

A serial number beginning with "5K" on a 3GS doesn't necessarily mean the device has been refurbished, just that it is an official replacement from Apple.

^No. It means it has been refurbished.
Ever wonder where the replacement phones come from?I always feel sorry for the guy in the iPhone commercials. He always gets a call right in the middle of trying to do something

My girlfriend took her white 3GS to a Genius bar because the case had started to crack near the silent switch. The guy replaced it with one from a plain white box insisting that it was brand new, unused. This was 6 weeks after the launch of the 3GS. I doubt they would have had many refurbs so early on. And believe me, it was in pristine condition.

I'm not complaining, just trying to understand!
