(adsbygoogle = window.adsbygoogle || []).push({}); Hi All,

Yeah I am a noob but am trying to learn. I only got an iphone 3g off a mate 1 week ago but have managed to jailbreak it, unlock it, and get cydia and installous happeneing.

Currently FW 3.1.2(7D11)
baseband is 05.11.07
Jailbroken with redsn0w
unlocked with ultrasn0w

Small issue I have found is that there are a few apps that want ios 4 and above to run so I thought about maybe upgrading the FW.

What I was to know is do I have to upgrade it to the ios 4 firmware through itunes first before I can jailbreak and unlock?

I downloaded IOS 4.0.1 as this seems to be the one that most of the apps I want are asking for and when I go to do a restore iTunes tells me it is going to verify it first so I bailed.
I read that apple have stopped signing firmware so dont know if this means that itunes will only allow the latest firmware via a restore?

My question is what is the best way to get to ios 4.0.1 and have it jailbroken and unlocked (currently locked to another provider).

I hear that redsn0w updates your baseband which is not desireable

Sn0wbreeze doesnt but in both cases I dont think I can just put a 4.0.1 FW straight over 3.1.2 FW without updating to 4.0.1 via itunes first)

Also, if I dont like the ios4 can I downgrade it back to 3.1.2? (as I hear some 3G phones becomes slow to a point where people feel they cant use it)

Thanks for your patience and help guys!

Thanks for your help guys, just one more thing. I used
Sn0wbreeze, have, jailbroken, unlocked and am on 4.2.1. Everything seems to be going well (had to get all my cydia apps/fixs again). However, the apps that I got off Installous that are synced to itunes wont restore back to the phone. I have installed Appsync 4.2, but from my understanding this will just allow me to sync apps I have now downloaded. What about the ones on my itunes account from my 3.1.2 firmware? Can I install Appsync 3.1.2 and it will work?
Thanks again for your help

as long as you have the appsync for your firmware, you can reinstall any app you have synced on to itunes.

i think you need to have saved the SHSH if you didn't the only thing you can update to is the latest FW which is right now 4.3.5 which i dont recommand

i think that u can do because u can re jailbreak on the latest firmware anyway,.....

Since you're using an iPhone 3G, I would recommand installing the modded iOS4 for iPhone 3G, it can be found at You must login or register to view this content.

I've installed it on one of my iPhones and it works great ! you have the speed of OS3 with the possibilities given by iOS4
