iPhone Firmware 4.3.4 and baseband 4.10.01 question jb with redsnow

[Xellos2099]

I got question, my friend want me to unlock his iphone 4 and it is Firmware 4.3.4 and baseband 4.10.01. I understand that I must use Gevey sim for it since the baseand is 4.10.01. As I was search for iclaried tutorial, I can't seems to find one for 4.3.4, only 4.3.3 and 4.3.5. Any idea why? Also, if I don't want to upgrade to ios5, can I skip the firmware reinstall and just do a reset on the phone and proceed to to jailbreak and unlock? Or do I must preserve the baseband and upgrade to ios5?

Another thing, my friend say the phone is never update and he got it when it launch but the firmware and baseband are updated at leasd once...

Only a tethered jailbreak for 4.3.4
Are there any hashes saved for the phone, use TinyUmbrella to check

Doubt it, the phone was never jailbreaked.

What are my option in jailbreak and unlock with a gevey ultra pro

No hashes means stay on 4.3.4 with Gevey to unlock.
Tethered jailbreak on 4.3.4

Updates to other firmware than iOS 6 (loosing the Gevey unlock) is not possible.

You can also look in to a IMEI unlock via greymarket.
Which carrier is the phone locked to?

Will Itune allow me to restore to 4.3.4 or it won't work without the SHSH?

 

[TriJetHero]

won't work without the hashes

If you don't need the jailbreak, just the unlock - pay for an IMEI unlock.
Then you can go to the newest firmware with no issues ever again.

Well, I already pay for the gevey sim already so might as well go through with it. So my only option would be reset the phone and jailbreak it since I can't restore the phone.

If you mean the erase all settings and content button, that will result in you haing to restore to current firmware.
