When I set up a new iphone and reset everything, does it erase cellular data too?

I got a Sprint 3G on my iPhone and I want to reset it. If I reset everything, does it erase the Cellular data with Sprint 3G too. Please I need to know so I can set up as new iPhone by using iTunes on the computer.

Yes it will erase all of your data.

That's pretty confusing how that is worded. The data that has been downloaded will be gone… So music you downloaded should be backed up first because it will be gone. You might be able to re-download it for free from itunes but I don't use apple products so I'm not sure if that's how it is set up. If you are asking if you will lose your internet connection, you won't. When your iphone connects to the sprint network, it'll automatically provision your data services.

People still use 3gs?

Yes. I think more to your point, it would likely erase the APN settings for Sprint. So if that is the case you'd need to put them back in.
