update to ios4 but unknow unlock method

[ppp885]

Hi,

I'm from Brazil and i bought my iphone at ebay, so I don't know if it's factory unlocked. I checked at cydia and I didn't find any source/app related to unlock, like blacksn0w, redsn0w and others.
My iphone is the MB046LL with firmware 05.11.07 and I'd like to know what I have to do to update to iOS 4.
Can i simply restore my iphone from itunes then update to iOS 4 and after that do the jailbreak? What's the problem with this procedure?
I can't understand when you say that first we have to update to iOS 4 then install Cydia, I mean, after update it, won't it be locked? so how can I access cydia!?

Thanks

3G, thanks

You can restore thru itunes to official 4.0.
Then follow this guide to JB it on windows using redsnow.

Then once its JB install ultrasnow from cydia to unlock it.

Don't I have to worry about firmware and boot loader versions. Downgrade to something... and all this stuff?!

thanks

No, thats just for 3GS models.
When it comes to 3G iphones its alot simpler

Plug it to itunes and click update.
And let it go thru and update your iphone 3G to 4.0.

Just Plug it to itunes and hit update.
Or just follow the tutorial with pics that I posted above.
Thats all.
Very simple.

ok,

just one more question.
i'm considering delete everything from my iphone. is there a problem if i click restore?

 

[Applejuiced]

Nope, its not a prob.
You can click restore also.

 

[ppp885]

but it'll restore to ios4 or the original version that came with the phone?

thanks for all the replies!

 

[ppp885]

do you know how to discover what unlock method was used?
remember that there is nothing related to unlock in cydia.

 

[Applejuiced]

Im done dude.
Just read and follow the tutorial I gave you. Thats all
Im not going to hold your hand and asnwer the same question 100 times. You gotta do it on your own.....
I like to help people but you are beyond help.
Find someone thats comfortable with computers and tech in general to do it for you.
