How to connect to internet on the road with PowerPC macs and Intel

Do you want to use your PowerPC mac when you are on the road? There is a simple solution, you will need a Apple iPhone (you can do it with android devices but I'm not sure how, google :) ) 

1. Go on your iPhone and enable personal hotspot.

2. Go on your Mac, and you should find your phone on the wifi network.

3. Connect and enjoy.

I wouldn't recommend watching videos on your computer :/ Your pretty much using your iPhone as a router. Any problems? Just comment me :)
