You need to provide more info. What phone OG or 3G. What firmware are you at and what do you want to downgrade to? Mac or PC? Are you just jaibroken or unlocked as well?

Hmmm, true dirty bird, never thought about that, even though, this has happened to me on my 2g phone going to 2.0 and downgrading to 1.1.4 on PC

You have to ask. You can't assume anything with people here. I was trying to help someone before and turns out they were trying to downgrade a 3G to 1.1.4 It's hopeless trying to help if they don't provide details. You also don't want to give them any advice because your advice could be based on assuming they are on a certain firmware or phone and it could do more harm then good.

ok I can't get a network signal but yet can make calls, I have not installed anything new lately, I just turned it on and can't get a signal plus voicemail isn't working. Anyone else having this issue this morning?

I have a Iphone 3G(S) 32 gb white, recently upgraded to 4.1 i have itunes 10 (latest version of it ) (jail broken ) it is not regnising my Sim card( Airtel , India )and i do not have any signal , it says "no service" what should i do ?

If you have restored to stock 4.1, the baseband cannot be unlocked. If you are using the unofficial carrier, then you are locked out.

how do i solve the problem of the Baseband, how do i unlock it ? (( New to IPHONe , sorry i do not knw the tech terms of it .. so yea )) and i know for a fact that Airtel , my Network is a official carrier . soo back to square one ...

If your sim card cannot recognize your iphone after restoring, then your carrier is not the official carrier for that iphone.

Baseband once upgraded , it cannot be downgraded.

so in short i am screwed ? and .. will it solve the problem if i get a new sim from this carrier?

[iYeow]

If you subsribe to the official carrier, then you can use your iphone.
