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

You have a 3G

and then if iTunes won't activate it (ie it's not factory unlocked) unlock with iClarified - iPhone - How to Unlock the iPhone 3G, 3GS Using UltraSn0w
