An update on my Iphone got interrupted, now it won't work or connect to my PC...

Hi. I was updating my Iphone 4 and I accidently disconnected it from my PC. I got en error in itunes that sad that it had been disconnected. Now when i turn my Iphone on i get the "connect to itunes" screen. I connect it to my PC but nothing happens. I try to restart my phone and try again but still nothing. I also tried switching USB port and restrating my PC but still won't work, my iphone is still stuck on the "connect to itunes" screen. I even tried to reset my iphone by holding the power and home button for 10sec but it didn't work.

I'm all out of ideas on how i can fix it. Could anyone please help me with this problem?

Thanks.
