I managed to successfully jailbreak initially, but then couldn't download cydia- now my phone displays the greenpoison logo on start-up and the app store is missing along with, bizarrely the calculator function on the phone...when i try to re-jailbreak, it says failed...any ideas? Cheers

while pressing shift - click on restore and restore back to 4.2.1 and run greenpois0n rc6-1 again.

restore your phone back to 4.2.1 (be careful if you need to unlock, let us know before steping anyfurther).

After restore is complete, attempt the greenpois0n jailbreak again, the first jailbreak obviously didn't complete corrrectly.

sounds dumb, but do you mean restore form backup? if i try to do a full restore it only gives me the option of downloading and updating to 4.3 which i obviously don't want to do...

press the SHIFT key while clicking the RESTORE button, a dialogue window will come up asking you to select the ipsw (firmware) file, you can download this (if its not already on your computer) from Apple, links to all ipsw file version can be found here

Once restored, you can try greenpois0n again.

You need to do this now while Apple still signs the old firmware 4.2.1 otherwise you will need to get TinyUmbrella and hope Cydia has saved your SHSH blob for 4.2.1
