How do I retrieve songs purchased on an un-synced iPhone that I no longer have access to ?

I recently purchased two songs via the iTunes Store for iPhone using my regular account; however, I cannot sync the phone to download the songs. How can I retrieve my purchases ?
Will everyone who purchased the iphone when it first came be eligible to purchase the 3G Iphone?

I feel that AT&T should give its customers the opportunity to go 3G. Do You think the will with this new iphone?
How do I cancel a application purchase for a iPhone after it has been purchased?

I purchased a application for my iPhone with my credit card. I forgot that I had cancelled that credit card earlier, therefore the card got declined when I purchased the application, yet it still downloaded onto my phone and works. The phone now tells me that I cant download anything else until I resolve the credit card problem. I would rather just not have the app anymore and not get charged for it, because I dont have another credit card yet.

How to download songs purchased on the Iphone Itunes store onto a new computer with itunes.?

I need to know how to get the songs purchased on my iphone, onto my computer so I can put it on my ipod.
