[yorkslad]

It depends on what firmware you have...?

[yorkslad]

how do i find that out ? got it 4.3.5

Only a tethered jailbreak available for you then

[joetwizzy]

yep only a tethered one. Which means you will not be able to turn your phone off or reboot without re jail breaking it.

Here is a quick guide if you decide to do it:
iOS 4.3.5 Jailbreak Possible with Redsn0w

maybe best to wait for the iOS 5 jailbreak

[yorkslad]

take it i cant down grade it then

[dik]

Not possible mate as it came on that firmware and you don't have saved shsh from previous firmware

[roryson]

when i got my iPgone4 it came with IOS 4.0. (jailbroke) i upgraded my software just recently to latest FW because i was having trouble, could i revert back to my 4.0 or just after so i can re jailbreak my phone. if not ill wait for new jailbreak, cheers guys..

[fijiman]

Only if you have your SHSH files saved via Cydia or tinyUmbrella

[roryson]

i think i saved those files with cydia

[fijiman]

Then you can roll back your firmware to whatever SHSH files you have...

[roryson]

but if im not jailbroke how can i use Cydia to roll back..?

[Funnyguy]

You can downgrade without SHSH aswell now using a software called iREB, you just need the firmware which you want to put onto your phone and restore using itunes then....If you google it you can find tutorials on how to do it
