@ipadone. i was thinking about your email problems... do you use an exchange account? there is well known and many documented cases of some versions of micro$loth exchange not playing well with any version of ios4 on ipt, iphone, or, now ipad. i have two exchange accounts, one is an older version of exchange which runs perfectly well on ios4, but another exchange is more current and doesn't play well with ios4, you have to bypass the exchange/push stuff and just set up IMAP till there is a fix. again, this has been a well known problem with all versions of ios4, not just the 4.2 beta. in fact, i had similar problems with 3.2.2, but on my iphone 3g on 3.1.2 it plays well with exchange.
