It seems that jailbreaking and unlocking don't sell so well on the internet anymore, so some sites reprofile themselves and promise to sell software that allows the installation of Android OS on iPhone terminals. There are few sites that do this, however this is among them and I warn you not to fall into their trap because only lies are presented there. They promise a software solution that for $30 allows you to install Android OS on iPhone 2G/3G/3GS, but in reality they don't have such a thing and Android OS can only be installed on iPhone 2G/3G.
There are free installation solutions on the internet, the best of them is Bootlace and it is available 100% free in Cydia. Android cannot be installed on the iPhone 3GS/4, iPad or iPod Touch 3G/4G because there is currently no software that allows this. Be very careful and if you come across something like this on the internet, I recommend you not to buy anything. I know that for some the idea of installing Android on the iPhone seems stupid, but there are people who want to try this and are looking for such programs.
