Hello Fellow MMI Members
I bought a iPhone3GS that has 4.3.5 iOS, Baseband 05.16.02 and jail Broken tethred because I see Cydia.
Is there a step by step to unlock? I cant buy that 30$ unlock tools hoping I can do it manually. If you have a step please or kindly provide.
Thank you for all your help

Once back on 4.1 fw you can run redsn0w 0.9.6rc16 and install the ipad baseband for the unlock and then cydia for an untethered jailbreak.
Redsn0w 0.9.6rc16 Released (Download Links)
After cydia is installed just install ultrasn0w and you will have your unlock.
This is the only way to unlock on any baseband past the 05.13.04 bb.
*side Note* You will lose GPS using the 06.15.00 ipad baseband

It wont let me downgrade... do i have to use itunes 10.0 instead of 10.4?

You can always create a custom 4.1 fw using sn0wbreeze and try restoring that way.
The newest version of redsn0w works tethered on 4.3.4-4.3.5 but there is no option to install the ipad baseband. The older versions of redsn0w that will install the required bb for unlock won't even recognize the 4.3.4-4.3.5 ipsw.

it downgraded to 4.1 but baseband is still the same... 05.16.02. I tried using Redsn0w and when applying baseband it just fails.
yeah this is not working.... getting pissed already. i hope someone will provide another solution

Thanks I got it to unlock. Here's my step.
If you have 4.3.5 with baseband 05.16.02
-Download 4.1 FW (not custom)
-run iTunes 10.4 and restore.
-use Redsn0w 0.9.6b6 to jailbreak first but DO NOT install the iPad baseband. Jailbreak it first and install CYDIA.
-Test if Cydia is there and active
-Run Redsn0w again and select install iPad Baseband. Let it flash Baseband.
-then run ultrasn0w to unlock
it worked for me from there after how many times i tried and restored.
Thanks to all

Im not trying to be a **** but if you are not familiar in jailbreaking. Its best to watch a youtube video. To be honest, i tried reading a lot on how to unlock and jailbreak but everyone has different ways of doing it. The video below worked for me.
This one worked for me... watch this youtube video.
