iPhone 3GS Jailbreak & Unlock 3gs

Do simple mode, and to see if you have the newest iPhone 3G, or not you can check the serial number.

I can't really explain it well. Read this

OK, so i ran tinyumbrella. The model number is:
MB489X/B - iPhone3G
and the serial is ***24

I had a look at this:
http://support.apple.com/kb/HT3939
and i am quite sure this is actually a iphone 3g. Not a 3gs. This is mainly indicated by the faded writing on the back, the apple logo is much brighter and the model number.

So it looks like my cousin go a bit confused and has actually bought a 3g then i just took what he said as fact...

Looks like we are back to square one. How should i approche the jb and unlock now that it has become clear that this is a 3g.

i am now following this:

edit:
NVM, the tut says:
Those of you who rely on a carrier unlock MUST STAY AWAY from Redsn0w and iOS 4.2.1.

That tutorial is outdated. 4.2.1 is jailbreakable now with ultrasn0w

So should i follow this then:
http://www.redmondpie.com/how-to-up...00-with-redsn0w-0.9.6b5-for-ios-4.2.1-unlock/

and then this:
http://www.redmondpie.com/unlock-4.2.1-ios-iphone-3gs-3g-with-ultrasn0w-how-to-guide/

looks like i will need to Update the Baseband to 06.15.00

Yeah. Looks like that's the only way to unlock it :/

You can't upgrade the iPhone 3G past that 4.2.1 anyways, but I think you lose GPS on your phone

Gps loss is ok.

For step two it says:
Update/Restore to iOS 4.2.1 firmware using the IPSW file you just downloaded via iTunes 10.1.

Just making sure i am interpreting that correctly, does it want me to update the IOS to the official 4.2.1 via itunes shift+restore.

Just press restore, and it should download 4.2.1, and update you to it.

Ok, i put the iphone into restore mode then clicked restore.

Okay. Just follow the rest of the tutorial, and you should be good. If you need anything else just post.
