These are instructions on how to jailbreak your iPhone 4 on the 4.3.3 firmware using RedSn0w for Windows.

Make sure not to update to iOS 4.3.3 if you need an unlock as one is not yet available!

Step One
Create a folder on your desktop called Pwnage

Download RedSn0w from here https://sites.google.com/a/iph.../redsn0w_win_0.9.6rc15.zip?attredirects=0&d=1 and place it in the Pwnage folder. Likewise, download the latest 4.3.3 firmware from below and place it in the same folder.

4.3.3 (4 GSM): http://appldnld.apple.com/iPhone4/041-1011.20110503.q7fGc/iPhone3,1_4.3.3_8J2_Restore.ipsw

Extract the RedSn0w zip file into the same folder.

Step Two
Connect your iPhone to the computer and launch iTunes.

Select your iPhone from the list of devices on the left. Now hold down Shift and click the Restore button. Restore is preferred as it won't create any wasted space on your iPhone.

Step Three
Once iTunes has finished updating your iPhone to the desired firmware open the Pwnage folder on your desktop and launch the redsn0w application from the redsn0w folder we extracted earlier.

**Windows 7 users may want to try running the redsn0w executable mode as an administrator in Windows Vista compatibility. You can do this by right clicking the executable and selecting Properties from the contextual menu.

Hold down both the Home button and the Power button for 10 seconds.

Step Thirteen
Once this is complete you will be notified that RedSn0w is done. Click the Finish button. When your iPhone finishes rebooting (5 minutes or so) it will be jailbroken with Cydia on the SpringBoard.

*As usual a big thanks to the iPhone Dev-Team and I0n1c for their hard work and contribution to the iPhone community.
**Windows 7 users may want to try running the redsn0w executable mode as an administrator in Windows Vista compatibility mode if you experience any trouble.

I can't download RedSn0w from your link
is there any other source you could give me
thanks a lot man
 
Is there a way to redownload Cydia onto your phone? I had my Verizon iPhone 4 flashed over to Cricket, but I cant send MMS. Everyone keeps telling me that Cydia will fix it, but that is not on my phone

The only way to do that would be to have your iPhone jailbroken with some sort of FTP or some sort of command line terminal like MobileTerminal from Cydia. Otherwise, in your case, you'll have to rejailbreak your iPhone and install Cydia, then reflash Cricket.
 
I've downloaded the latest redsn0w but when I click on properties it doesn't ask to run in service pack 3 on mine ,only 2 .im on vista will that make a difference ? I get to the 1st done screen loads of text on the phone then it stops with please wait ,no pineapple lol ? What u guys reckon ? Also will this enable me to use a diff network as its locked to a carrier

Thanks in advance
 
Can you be a little more in-depth about the process that you took when trying to restore? And no, jailbreaking =/= unlocking. The only way to software unlock an iPhone 4 using UltraSn0w is if the baseband is 01.59.00. Otherwise, with a certain combination of baseband and iOS, you can use an interposer like the Gevey or you can IMEI unlock it, which has no requirements for iOS and baseband
