Need to unlock 3GS 4.3.5

[harryml]

HI,

I just got iPhone for my dad 4.3.5 and want to unlock it, so he can use it in different carrier. The version right now is 4.3.5. I have checked the internet and i couldnt find anything reliable. I don't want to brick my phone, so looking for step by step instructions.

I don't have any older SHSH or i don't want tethered version.

Pls help

Thanks

I don't think 4.3.5 can be jailbroken or unlocked.

The only option the OP has is to upgrade to iOS 5 and jailbreak tethered. You can't downgrade due to the lack of SHSH's.

I cant use someone else SHSH which is on the net.

I wish that were possible, but it's not unfortunately. If you don't have the relevant SHSH's you cannot downgrade or upgrade to a specific firmware.

Is there a way i can downgrade to a lower version and then unlock it?

No, that's what you need the SHSH's for.

You can use a tethered jailbreak for 4.3.5, but you won't be able to use an untethered jailbreak since you don't have any SHSHs for older firmware and thereforee cannot downgrade.

If you just want to unlock, buy a GEVEY SIM. No jailbreak is required and it works on 4.3.5.
