need to jailbreak my iphone 4?

There is no jailbreak for 4.0.2 and iPhone 4

If Apple is still signing 4.0.1, restore to 4.0.1, then run jailbreak.me

And get tinyumbrella and start saving your hashes.

Most important rule if you expect to stay jailbroken...Never update your firmware until after new tools are released (and there will likely not be 4.0.2 jailbreak since Apple will be releasing 4.1 fairly soon)
 
If you don't have 4.0.1 SHSH saved, you're out of luck until and if DevTeam comes up with a jailbreak. Apple is no longer signing 4.0.1.
 
If you don't have your SHSH blobs for 4.0.1, I think you are out of luck until 4.1 comes out.

Don't hold your head underwater waiting for a 4.0.2 jailbreak. :cool:
 
Doubt they will be releasing a Jailbreak for 4.0.2 (ip4)... The only thing it fixes is the PDF exploit and that can be fixed with a cydia package anyway. If they have an exploit available right now they'll be saving it for 4.1 (shouldn't be too far off anyay).
