There is no iPhone OS version "3.3". If you are referring to iPhone OS 3.1.3 please search Answers.com as I'm sure this question has been asked.
Go to openiboot.com/or jailbreak ur iPod 1g and get bootlace and install android its a totally new OS its not just a theme
This I am not sure about but I think that when you install it iTunes is not able to restore the iPod touch, you have to manually reformat and install the iPod Touch OS which is tricky and usertain weather it will work.
Os 3.1.3
I'm betting that you have a iPod Touch. Right now you can't put a background on your apps page unless you jailbreak. But, if you have an iPhone 4 you can do it without jailbreaking. If you don't have OS 4.0 or above, you can jailbreak. Here's how. On your apple mobile device, open up Safari and type in this address, JailbreakMe.com Slide to jailbreak!
If you have a wifi connection, then yes. Youtube is part of the current iPod Touch / iPhone OS.
Adobe Flash Player is not supported on iPhone OS (iPod Touch, iPhone and iPad). In short, you can't.
iPods can only play music, except for the iPod touch. The iPod touch does not run mac OS X, it runs on its own mobile version for everything. iPods are not computers, they are music players.
You have to manually update the OS and apps
