Sorry if this has been asked before... I just downloaded the AIM app for my new iPod touch and it's not working. I told a friend to come on so I could try it out and it says that they're not on and the IM I type in does not send. I'm also having trouble sending e-mail through the mail icon on the home screen of the iPod touch. Whenever I try to send an e-mail to someone, the e-mail does not send because it says that the address was invalid. Anybody know what I'm doing wrong here?
