I was able to set up my MSN account on my new iphone.. however.. it will only receive mail.. it will not send it.  I keep getting an error message that my email user ID or password is incorrect.  I have tried to delete the account and reinstall it on my phone, but am still getting the same message.  Since I am receiving emails.. this message cannot be accurate.. since I wouldn't be getting emails in if the user ID or password was incorrect.
