I am really confused about jail breaking

[thegameplayer]

I just got my iPhone 4 today and i want to jail break it but i don't know how to. The guides here are not detailed enough for me. I have 4.1 iOS and baseband 02.10.04, do i need to install iTunes on my computer and do something to iTunes on my iPhone? I also don't have any SIM card at the moment.

[iYeow]

Yes, you have to install itunes first, you can hactivate and jailbreak your iphone 4 with Limera1n.

Limera1n or greenpoison should do. Also download tiny umbrella and save your 4.1 SHSH while you still can.

X98car, I see that you have updated your iphone 4 to IOS 4.2.1, what's new in this update.

Ok, so first i install iTunes 10 then i download limera1n or greenpoison (which is better?) I connect my iPhone to iTunes on my computer then run limera1n, then it's jailbroken? When do i use tiny umbrella? Will there be any problems if i do get a sim card in the future?

If you are with official carrier, when you get your sim card,do a restore again, put your sim to activate and then jailbreak with Limera1n.
When you open up Cydia for the first time, a message will display, just say Yes, make my life easier, all future shsh blogs will be saved for you.

Ya I can never wait when an update comes out, gotta jump on it and deal with the consequences later

I mainly did it for the airplay. I have a Apple Tv so they work well together.

How would i do a restore?

[Simon]

You would download the 4.1 firmware and then hold shift while clicking restore in itunes. A window will pop up where you can choose the 4.1 firmware. But it will only work later on if you save your 4.1 SHSH with tiny umbrella now.

[thegameplayer]

Am i not able to save my SHSH anymore because apple stopped signing 4.1? Is it still worth trying to jailbreak now?

[Simon]

You can still save your SHSH for 4.1 now. But do it soon as they could pull the plug at any minute.

I just tried to jailbreaked with greenpoison and i messed up with the dfu mode. now im in recovery mode. what do i do now?

[Simon]

Try it again.

[thegameplayer]

i was able to jailbreak but when i went into the loader it installed cydia but after i restart the i4, cydia is not there but the loader is, when i go on the loader it just puts me back to the first springboard.

[Simon]

have you tried rebooting?

[thegameplayer]

i just rebooted and its the loader is still there but no cydia. should i install cydia again?

[Simon]

If it will let you. Seems greenpoison can have these issues sometimes. Maybe you should try Limera1n instead.

[thegameplayer]

i reinstalled cydia and it works now, thanks man your the best, right next to michael jordan.

[Simon]

You couldn't have said Kobe?

Glad you got it working
