Update to iOS4 erases iPhone songs, videos?

[brsedu]

I forget what happens when we update to new firmware on an existing phone: Does it delete the music/video content from the iPhone? Or is there a way to preserve this content when I load the new iOS4 later today on my 3GS? I know you can preserve photos, text message threads, apps, etc.

My iPhone 3GS is backed up.

If you restore from backup you'll be fine.

I do not remember having to re-sync everything for the prior updates.

i didnt restore or anything.

itunes says new software available, i said to download and install and 16 minutes later my phone had a new screen.

didnt have to do anything else.

all my songs, videos and pictures were still there after the upgrade on 3gs.

all the apps are still there, bookmarks, contacts, everything.

Awesome. Thanks for the info. Looking forward to not having to reload all the media.
