Hey I jailbroke and installed cydia on my iphone 4 with iOS 4.2.1 using greenpois0n, I tried to restore everything in the iPhone settings with the option erase all, now the iphone only shows the apple logo, in 30 or 45 seconds the skull of greenpois0n appears and it gets frozen... what can I do?

You shouldn't have doen that particular thing "Erase All Settings".

Your only way out is by restore.

If you have selected in Cydis "To make your life easier", this would have saved your SHSH keys on Cydia server for 4.2.1 to allow you do a selective restore to 4.2.1. Otherwise you will have to restore to 4.3 for which a complete jailbreak is not available yet.

Or even a partial one, far as I can tell ;)

Get latest TinyUmbrella from here run it and in "Advanced" tab make sure the box for "Set Hosts to Cydia on Exit" is c hecked, then exit the software. Next try to a selective restore in iTunes by holding the SHIFT key and clicking the RESTORE button, when the window comes up asking for the ipsw file you should point to the correct location of the 4.2.1 ipsw file for your device, you can get to download that from here if you dont have it already on your computer

@spockers check this

Our best bit is for @i0n1c jailbreak, he has demoed a 4.3 jailbreak, but he will not release before 4.3.1 is out. It would be interesting to learn if he found a way around ASLR.

Have tried that, many times. I can never restore to the ipsw it creates, on my iPod or iPad, I get iTunes error 1, which is very difficult to search ;)
