Port forwarding on 2wire router

I'm having trouble port forwarding for an app called iVigilo (It's turns an iphone/ipod into a wireless ip camera, it has settings for port forwarding also) On the computer in my router settings, under firewall I added an application for it (but it didn't work):

What do I have to do to get the camera t owork outside my network?

Is there anyway to retrieve old notes from iCloud?

I have iCloud turned on and i noticed that you have your notes from your iPhone saved onto your email on your mac. I thought that this meant the copy of the old notes was forever on the email no matter what changes you make to it.recently i deleted all my notes to make room for my phone but i realized that by doing that, it deleted the old copy of the notes off my email as well. Is there any way to get them back considering they used to be on my email before?

With itunes and iphone. Pretty Please

Okay so i'm seriously about to pull my hair out. I have an Iphone 4 and recently purchased a new laptop. After I installed itunes on it, I went to sync my Iphone, figuring everything would just be transferred to the new itunes as it had in the past. When the download for IOS5 completed, I still had my contacts/pictures but my music and apps were wiped clean. I downloaded my apps again and I figured I would just start putting cd's I had with me in my library. I added about two cds and when I went to sync, I was informed that my phone was authorized on more than 5 computers. I deauthorized it from one but it still won't let me put the music in my library onto my phone.

Can anyone help me? I would greatly appreciate it.

Added (1). And when I try to drag songs individually, a little circle with a line appears and it won't let me.

How to automatically send blocked numbers to voicemail on my Iphone?

I'm being harassed by someone calling me from a blocked number on my Iphone. This person calls me repeatedly at all hours of the night, sometimes 30-40 times in a row. I don't want to have to change my number and I'm wondering if there's an App or something that will automatically send blocked numbers to voicemail without me having to push the button to send the call there. Any help would be greatly appreciated, thank you!
