iPod Touch Music download

Is there a way (without Jailbreaking) that I can get an iPod Touch to download music straight from online? I saw dTunes, but I have to jailbreak for it.

Also, if there isn't a way, is Jailbreaking safe? I assume that it will void my warranty, as Linux did to my old iPod.

Oh yeah, and one more question. I might get a 1G Touch. What is different between the 1G and 2G Touches? Do all the apps work on 1G?

Thanks for any help.

The iTunes Music Store might be a good start...

About the 1G and 2G iPod touches - the only difference that I know of is that the 2G has an internal speaker and the 1G doesn't. And yes, you can go on the iTunes music store on your iPod Touch as well.

I know about the iTunes Music store , but I guess that is the only way to get it directly on it. Is there a way to connect via FTP to it (Go -> Connect to Server)?

Thanks for the info about 1G vs 2G. I didn't even know 2G had an internal speaker.

2G has a faster processor as well.

You're not talking about illegal downloading now are you?

Absolutely not. Most of the bands I listen to aren't signed and have free music for download on their websites.

^ Get 2G. Its newer, has faster processor, has bluetooth which will get support in iPhone OS 3.0 and has a volume rocker & an external speaker.
Plus, iPod Touch 2G supports microphones, 1G doesnt.

Thats it. 2G has been jailbroken if thats essential to you.
