I have an iPad with 3.2.1 which I jailbroke using jailbreakme.com. I have never upgraded since and I was wondering if its worth upgrading to 4.2.1 and how difficult it is to JB. The website jailbreak was so easy that I could not resist but I don't have alot of experience at this type of thing. I have noticed some newer apps are requiring 4.0 and higher so I guess I will eventually need to upgrade. I was looking into the VM memory hack and noticed several references that 4.2.1 has this native capability. Overall i'm satisfied with the performance as is but would appreciate your thoughts on whether its time to upgrade and JB again. Thanks.
