You should regularly be backing up the phone to ensure your data is safe.
Media, contacts, and apps are NOT included in the backup.
If something goes wrong with the update and you have no backup you will lose all data.
Do you want to take that chance?

I CAN NOT back up my phone, iTunes on the only computer in my house is taken up by my brothers iPhone. I'm just asking if it is safe to update my phone.

You can back up multiple iPhones to the same computer. See: http://support.apple.com/kb/HT1495
And the answer is NO, do not update it if you don't have a backup on a computer. The risk of something going wrong is small, but you will be stuck with an iBrick if something does go wrong.
BTW Contacts ARE included in the backup, but not media or apps.
