3GS- lost backup file, how can I create a new backup file

[Foxtrot01]

My computer crashed and I dont have a way to get the original backup file. I have a new computer and I need to create a backup since I am replacing my 3GS with another 3GS tomorrow.
How can I do this? I dont want to loose the pics, MMS, SMS or contacts.
I saw another thread but the thread is about retrieving the old backup file from an old computer. In this case I dont have the old backup file, I need to find a way to create a new one if possible. Please help.

Just make another backup in iTunes.

Use sharepod (Windows) or expod (Mac) to get your music off the iPhone. sharepod can also get your pics off. Use image capture on a Mac to get camera roll pics.
