anyone else experience the same? first time round with the update to 4.1 my phone got stuck with the install of the update and gave me error 1004. i had to take my phone to apple and got a replacement. same thing happened with the 4.2 update and this time i got error 1013. i did some research and got it fixed by opening terminal and amending a line of text in the host file. so this is quite obviously going to happen again with the next update and i'm wondering whether there isn't something on my macbook which causes this problem. if anyone's got advice that'll be appreciated.
