Hey guys. Just joined the forum. I'm on JPC Froyo Firmware now. Wanted to ask a suggestion from you guys. I wanna try the Voodoo lagfix but I read it's good only on Eclair firmwares. I see that JM8 is the latest eclair firmware available. So the suggestion I need is, what's the best Eclair firmware that you guys have used and whether the really old update.zip rooting method on XDA would still work on the newer firmwares like JM7 and JM8?

I used JG5 before going to JPC and I know JG5 was easily rooted with the update.zip file on XDA (on the huge Galaxy S thread). Would appreciate any help.

I have the Singtel Galaxy S i9000.

Sorry, but what is the 'sales code changing key'? What is that for?
