You might alreaedy have one since android is simply an
operating system and set of applications that are aiming to be neutral of the phone on which they run as opposed to having a specific OS from your phones manufacturer (e.g. Nokia's OS is Symbian). All you need to do is make sure you've got a "smart-phone" and contract that gives you net access and you should be able to use android when its finally released for your phones OS (although installing it will no doubt void the warranty your contract provides, so it will be interesting to see how this pans out, will phone manufacturers adopt android, will mobile providers opt to install it in favour of the manufacturers OS?).
