use greepoison and it has a way of getting around the error code 1013,worked a treat for me,obviously make sure you back up via itunes before you start and get the latest version of itunes on your mac/pc,i take it you got your shsh saved on tiny umbrella ?
good luck,any probs check back on here for loads of help

what does this mean ?

if you want to restore your phone back to an older firmware version you will need to have your shsh blobs saved via a proggy called tiny umbrella,if yoiu do a little search on the net you will find heaps of info on saving shsh,its simple to do and as i said it allows you to restore back to an older firmware version after you jailbreak your phone

so if im trying to update to say 4.3 i take it i dont need the shsh, i can just do it from i-tunes ??

if youre jailbroken already dont update to 4.3 as theres no jb for it at the moment
