So Apple signs the baseband? Then how come nobody has figured out how to save the signatures for the basebands, so people can downgrade their baseband if they "accidentally" update it?

that is because the baseband shsh signatures is far more secure than the firmware one, in that every time you request it, it will come back different.
 
Thanks 4 your kind info.

I bought my iphone 4 from UK

But I live in Dhaka, Bangladesh.
Better to wait until dev team release new unlock tool for 4.2.

You could call them up and see if they can do the process over the phone to unlock your iPhone officially....
 
Is there any way to downgrade BB one step more 2.10.04 to 1.59.00

THANKS...

wtf?

Did you actually read nebo1ss's respond? I believe he clearly stated the reason why you are able to downgrade your baseband.

Keep your imagination to yourself because you don't even know that you need PwnageTool to preserve his baseband.

Are you even an App developer?

gngan i know it's not possible to downgrade BB.

Anyway guys, I need some help please.
I bought my iphone 4 from UK. It's factory unlocked model
MC603B

Whether or not it can be unlocked is up to the carrier. Don't waste your time asking on forums, contact O2. Is it safe? Well, of course it is! Why wouldn't it be? In fact, it's more than safe, once it's officially unlocked, you never have to worry again about accidentally updating your baseband!

You are providing conflicting information on the source of your phone. In an earlier post you stated it was purchased from O2 now you are saying Orange. Also your phone is not a factory unlock model. In the UK you only get a factory unlock model if you buy it at the Apple store. That is where you should have purchased your phone in the first place.

The unlock procedure from o2 is published on their web site.

Orange also has a similar procedure.

However, Since the IP4 is so new I am not sure that they have starting unlocking them yet.

In both cases you need a pay and go SIM card from the carrier with enough Credit on it for them to deduct the unlock fee, Sterling 15 for O2 and Sterling 20 for Orange.

Because I have no orange sim....to unlock I need orange sim.

Thanks 4 your input...but I am not in UK.

I live in Bangladesh...our country no orange support.
I purchase IP4 from Bangladesh...my friends friends bought it from UK

Don't you know anyone in UK that can buy one and ship it to you? Or isn't there an ebay or craiglist in Bangladesh?

Need Help PLS

restore with 4.0 firmware from internet
 
restore with 4.0 firmware from internet

And how may I ask is he going to do that without SHSH? Even if he could how would that help him. The 2.10 baseband is not going to downgrade to 1.59. Did you even bother to read the thread?

No man...I don't know anyone in UK.

I had couple of conversation with orange UK.
Try to convince them, but it didn't work. They need the original sim that came with IP4 to unlock it...also they need at least 3 month to use the sim and then they will be able to unlock it officially.

I am really helpless. is there any solution.

PLS kindly suggest me.
