cool, thanks for the info. I'm not worried about the bb since I use at&t anyway.

Lol Basehand Hahahahaahhahaahahaha

So in a nutshell, in all our haste to upgrade this fone NO one has figured out how to clone the original baseband and dump it like they did with the unlock. Now that makes no technical sense.....

I'm really sorry if this sounds like a dumb question but what is Baseband and why would it be important to downgrade it?

Thanks in advance for your detailed responses.

Maybe this question could be moved into another thread or its own thread if it's too off-topic for this one.

Why would anyone want to downgrade now that 1.1.1 has been jailbreaked (jailbroken?)

Shortly all the apps will be ported over to 1.1.1 and you will have all the benefits of 1.1.1 and 1.0.2

Is there anything about 1.0.2 that is better?

**McGeeTM** · 10-10-2007, 12:16 PM

it works! woot! i could never downgrade until now

thanks!

Baseband, I guess is a techy term for the iPhone modem. It's what lets your iPhone be a phone. It's important to downgrade, because an iPhone cannot be unlocked (currently) after it has been updated to version 1.1.1; even if you then downgrade back to 1.0.2. This is because downgrading from 1.1.1 back to 1.0.2 does not downgrade the modem firmware (baseband). So the phone can't be unlocked.

Unlocking simply means the iPhone can be used with carriers other than AT&T.

That good enough?

I assume that I can use a windows computer to do the downgrade and it will still work on a mac. Am I correct?

**McGeeTM** · 10-10-2007, 02:09 PM

Alrighty, i just downgraded using the new ibrickr and finished it up and went to applications to install installer.app then gives me an error saying "iphoneinterface.exe has encountered a problem and needs to close. We are sorry for the inconvenience."

then it just sits there frozen

After you get your iphone back to 1.0.2 with iBrickr (v09), try using iBrickr v(08) to load all your apps.

**t.storbeck** · 10-10-2007, 03:47 PM

i had 1.1.1 then downgraded to 1.0.2 now i changed my mine and want to go back to 1.1.1
ibrickr is saying "Your iPhone has not been freed yet. Click the button below to get started."
Does this mean i am NOT unlocked? if so can I update to 1.1.1 w/o bricking?

Someone please help me!
