I have a powerbook g4 version 10.4.11 but my iphone won't connect to it?

Us there like a update or something because I can't iTunes, I can't download adobe and I can't connect my iphone. I plug it in but it won't show up. I used three different chargers and also my iPod they won't connect and I download a whole lot of music and I can't download them.

The G4 PowerBooks were discontinued many years ago. They can be updated to OS X 10.5.8 (Leopard) but even when updated they will not be able to run the latest versions of software such as iTunes or Adobe's Flash Player. You will not be able to connect an iPhone with the G4 PowerBook.
