First of all, it's quite obvious that the Ipod Touch can NEVER be transformed into the IPhone - as in, you will never be able to make calls with the touch. Based on the capabilities, it's pretty obvious that it is not a phone, if that's what you want. And as for Installer, it is only accessible through jailbreak. What you can do is with Installer, you can install the original IPhone applications (mail, maps, notes, stocks). Jailbreak is quite a delicate process though, and I'm not quite confident that you can successfully complete it, as you need to have a really good understanding of how the Ipod works in order to jailbreak and fix bugs. Either get someone to do it for you, or simply leave it as it is.
