How to delete a song from my iPhone 4S?

Before the new software updates from Apple, I could just swipe the song on my iPhone and press delete when it came up, but now that function doesn't work and I haven't a clue how to delete songs from it.

I can delete them in my iTunes library but they still stay on my iPhone which is really quite annoying.

Anyone have any suggestions?

Want to buy an iPhone in USA?

I have got a relative living in the US. Can he order an iphone from apple store online with some carrier (not unlocked one) and get it to my country? It turns out to be a lot cheaper. For eg: If he orders an iphone 4s with AT&T carrier, it will cost around $99 (for the phone) + $50 (approx. For activation and such).So maximum it will cost around $150-160. I can unlock the device here for very very less price. My relative can select some PAY-PER-USE plan but he won't use it at all in USA, n so he won't be charged of it. Is that okay? Will it be considered in any way as illegal?
