I update ma iphone 4 to 4.1 but its bb is 3.10.01 i know unlock is not released.
I want to know that why my youtube is not workin it says can't connect to you tube.
Please help me...

I've jailbreak with Limera1n.

And does new unlock support my bb 3.10.01 of iOS 4.1(8B117) ?

Abd Can you tell me how i know from which country this iphone comes ?

Your baseband/iOS combination suggests you upgraded to iiOS 4.2.1 then downgraded to 4.1 (and you did this with a saved SHSH)

Limera1n's hacktivation is pretty crap, this might be the cause of your problem.

We recommend redsn0w for 4.1 and greenpois0n for 4.2.1
Also, once an updated ultrasn0w is released that works on that baseband, we recommend you re-activate using SAM/ultrasn0w.

While you are waiting, you can try to install the youtube fix that is available on the cydia.pushfix.info repo - that might fix it.

I've already tried downgrade but its not working.

and give me grief info on shsh.

And also tell me about SAM.

I can't upgrade ma 4.1 to 4.2.1 its give me error 1013 and i delete ip from host file

What to do now ?

I gave you a short-term solution install youtube fix cydia.pushfix.info repo - that might fix it.

Otherwise
Do you have access to a mac? Have you tried a custom IPSW made with Pwnagetool 4.2?

Alternatively, have you tried this procedure to restore to 4.2.1 thefirmwareumbrella.blogspot.com/p/prevent-iphone4-baseband-update.html
That procedure should not be necessary for you - but if you have had no luck getting past the 1013 error, it will probably help.

I have windows and I succeed to upgrade to 4.2.1 but now i want to know that greenposi0n don't work for me so i tried redsn0w it works n you tubes also works fine but what does tethered jailbreak means ?

And whats its benefits and looses ?

You need to use a combination of first greenpois0n and then redsn0w to jailbreak untethered and hacktivate 4.2.1

If you search around, you will see that I have explained this procedure many times.

can you give me your link where you explain it(jailbreak untethered and hacktivate 4.2.1) ?

It's really not hard to search.

Restore iOS 4.2.1
Run greenpois0n rc6.1 or higher to jailbreak
run redsn0w 0.9.6rc8 and after supplying the same 4.2.1 IPSW you used to restore the phone, select only "install cydia" - make sure you have a SIM card in the phone that iTunes says can't be used to activate.

ohk I've search it.

I did jailbreak by greenposi0n and then by redsn0w 0.9.6rc8.

But I've problem that i installed installous from cydia and download few ipa files from there and when i connect to my itunes i can't transfer this ips files to my computer cn u tell me how i transfer this file to my computer ?

We don't endorse piracy here at hackint0sh.org

Most software from the iOS AppStore costs less than a cup of coffee at a cafe.
You risk viruses and malware by installing pirated software.

Take it from me, there are no justifications for piracy. If you have paid for an expensive phone and contract, you should have budgeted for the cost of apps.

Don't ask about piracy again.
