I upgraded from 3.2.1 to 4.2.1 and not only its not slower,its noticeably faster too.
You've hit the nail on the head here Jonny.
My problem is with content, which is backed up - that was imported by the camera kit. Its a load of photos from my wedding/honeymoon which i cant get back onto my iPad (just stuck in my backup)
Im wondering if i revert back to 3.2.2, then try restore from backup - i might get them back - fingers crossed.
what do you think?
I think that as long as those photos are on your machine you should be fine when you restore.
I'm also finding the return to home screen animation sometimes doesn't seem to run or stutters a bit.I went through a day of usage and Safari managed to maintain 2 tabs over the 14 hour period. That I did not expect.
Unfortunately, that's my only praise of it, folder animations are laggy, when navigating back to the home screen the animation either stutters or just doesn't run and it can't take anymore than 6 apps at any one time without flushing.
