I got a blue and white power mac g3 tower running jaguar 10.3.9 Looking into upgrading it a little bit to get to know macs and the programs. Is this a good idea? I want to basically use this for the simple purpose of jailbreaking my iphone and taking advantage of the mac only programs for it I know i need to upgrade the memory and i seen 1gb sticks could i pop 4 of them in and get 4gb and go upgrade to tiger?
