4.2.1 Greenpois0n

Quick question:
My friend is already running 4.2.1, can I just run GP and get the cydia loader and then just keep working with all his apps and other stuff? Or do you GP with a restored/empty phone?? I've never done this way as I usually perserve baseband and have a clean phone to jailbreak on.
Thanx in Advance.

Hey guys, I think Im in the mood to finally jailbreak. Ive seen a ton of complaints of issues with the untethered jailbreak. I just wanted to know if the windows version installed and working well for everyone and if cydia is installing and working fine now.
Thanks
Thanks
I jailboke my iPhone 4 a few hrs ago using this tool and it works great! I haven't had any problems so far, and everything is running smoothly. I love it!
I dabbled a little bit with the tethered jailbreak offered by redsn0w, but ran into problems so I was waiting for this and / or 4.3 unthethered jailbreak.
That's just about it.

Upgrading 3GS 4.0 --> 4.2.1 questions
Hi guys,
I wanted to run my scenario by you and see if you had advice if I am on the right track to successfully JB'ing my iPhone with minimal issues.
Here's my current scenario:
3GS, old bootrom, 04.26.08 baseband, 4.0 JB with sn0wbreeze, unlocked with ultrasn0w.
I want to update to 4.2.1 + JB + unlock if possible.
It seems like redsn0w or GP are my two options, but I would like to maintain my baseband and keep GPS if possible. Keeping unlock capability is less of a desire at this point.
My tentative approach is as follows:
0) Backup phone in iTunes + PKGbackup for JB apps
1) Perform standard FW update to 4.2.1 via iTunes
2) JB with greenpois0n RC5_b4
will this approach preserve my BB, and give untethered JB, but no unlock capability?
Is it worth keeping current BB, or upgrading to iPad BB 6.15? I'd hate to lose GPS!

Yes, there's no real need to Restore to a clean 4.2.1 before you apply the JB
The only small snag with this JB and also previous 4.x ones is with iBooks and DRM-protected books. That combination just won't work.
Meh, i dont even use ibooks....so cydia is working perfectly & installing perfectly fine with greenposion then?
thanks
This approach won't preserve the 04.26.08 baseband, updating via standard iTunes Restore process always applies the latest fw and baseband. This means you won't be able to unlock any time soon, possible never.
Seeing you sit with the beloved 04.26.08 baseband (resale value) I would definetely recommend building your own Custom 4.2.1 IPSW with PwnageTool (or as last resort the upcoming release of sn0wbreeze) or use Redsn0w.
Unless you're really desperate - don't go down the iPad baseband path
I see. So more appropriate method would be:
0) Backup phone in iTunes + PKGbackup for JB apps
1) Build custom IPSW 4.2.1 using PwnageTool, which preserves current BB
2) Perform FW update to 4.2.1 custom package from step 1 via iTunes
3) JB with greenpois0n RC5_b4
With this, I'd jailbreak, preserve BB, and have unlocking capability intact?
If you build a Custom IPSW with PwnageTool you won't need Greenpois0n. Just do 0-2 and you're done, jailbroken and all.
However, Dev-Team is only allowed to incorporate the untethered Greenpois0n exploit (called feedface...) in PwnageTool sometime today or tomorrow so you need to wait for an update to PwnageTool.
Hi, Anyone else having issues with JBing an iPhone 4 on 4.2.1 for Mac? I'm following instructions exactly, puting my phone into DFU, it says it's jail breaking, then it says "Failed 
" and my phone just restarts normally. I'm not sure what's going on. Can anyone help?

You must keep pressing the home button until it finishes jbing. Do this many times if needed, mine jailbroke in the 5th attempt
Just a few observations that I noted:
Jailbreak went perfect (I have a 3GS). No issues doing the actual jailbreak. After the jailbreak I had a few problems.
Battery Drain. The battery drained out at a rate about twice what it was before the jailbreak. I have jailbroken the same phone before, and never had this problem. This wasn't the deal breaker though.
Slow restart. It would take about three to four times as long to restart after shut down. The GP symbol would be on the screen and it would take some time to get things running again. Still not a deal breaker.
Freezing during calls. This was the deal breaker. It continuously, I would say one out of every three calls, freeze up and have to be restarted, and this happened during the telephone calls themselves. This was the deal breaker for me.
It's really too bad. Other then the obvious fun in customizing your phone (which should so be a stock option), or custom sms tones (which should have been done from day 1) the jailbreak apps like bitesms are so wonderful to have.

These all sound like serious issues to me, any one of which might give a person pause when jailbreaking.
Anyone else having these issues?
Thanks...also good info for MikePA since the traditional way does not work.
Oh yeah, I alos tried to jail break it using windows, and still nothing
. I'm not sure what's going on.
Do your own research to be sure but I believe that 4.2.1 stock on a 3GS is unlockable... According to this web site http://jailbreakmatrix.com/iPhone-iTouch-Jailbreak check it out!
I have exactly the same issue with 3GS. Will jailbreaking it with GP make it untethered and will it fix the GPS issue?
