I want to get this out there one last time - You can still Jailbreak your Ipad2 thats wifi running 4.3 even though it is past the window!!!!!! There is a work around for the 403 error - I actually Jailbroke my Ipad 2 Sunday night at around 11:30pm, way past the window of opportunity. It takes a little bit of time (took me about 45min), and you need to download some pretty sketchy software,,,,,,,,,,,,but it works! I dont think that I am allowed to link to youtube, but just search there for "get around 403".
Attached is a pic of my homescreen
