My new iPhone won't connect to computer?

I got a brand new iPhone on Saturday and need to connect it to my computer for the first time. When I try it won't show up under devices on iTunes and it won't even show up on my computer. When I plug it in I do hear a small 'bong' which indicates something has been connected but that's it. Nothing else happens. I have made sure my iTunes is on the highest possible software, I have turned it off and restarted both my computer and iPhone. Nothing seems to work. I have been trying for hours, on both Sunday and Monday… What shall I do? Any ideas?

Added (1). I have already set it up by the way, I just need to do something that can't be done without syncing

Can i ask Vodafone for an iphone Sim?

I have recently started a 24 month contract with Vodafone in the UK, with a Samsung galaxy s2 included in the monthly price. After 2 months of use I've decided i'd prefer an iphone 4.

Would i be able to ask Vodafone to transfer me to a mini Sim card or would they take the view that i have to stay with the s2?

Why is my Iphone 4 not showing the contact names on my in-coming texts?

I'm having this issue with my Iphone 4 after updating. Suddenly my text messages are not displaying the contact name, but rather just the phone number of the person sending the text. It always displayed the senders name prior to updating, and now I can;t get it to return doing so. I've tried rebooting my phone and tried to look up some info on the net, but nothing seems to work to get it back. Has anyone experienced anything similar and if so, how did you fix the issue.

Can I use an iPhone 5 from Verizon with AT&T or T-mobile?

I have an upgrade with Verizon and I'm wanting to use it to buy my friend an iPhone 5 for Christmas. Only problem is that she has T-mobile. If I do the upgrade with Verizon will she be able to use it? I was told that I would have to have the micro sim card taken out and have a new one put in from an apple store. That's just what one person told me. Any help or advice would be great.

Missing iphone desktop icon? I want to move music files to new Mac?

I just got a MacBook Pro and I wanted to move my music to the mac but none were purchased through iTunes so the option iTunes has doesn't work… My ipod and iphone icons aren't showing up on my desktop so I don't know where to go to manually move the files into iTunes. I have tried a lot of the stuff on the web but nothings working. Anyone know?

Added (1). I actually want my music to move from my iPhone to my mac, so putting on a thumb drive (to transport from computer to computer) wouldn't work. I have found online that if you can find the iPod files you can move them manually but I can't find the files anywhere.
