To answer your questions
Android is an Operating System. Just like Windows XP, Mac OS or
Windows Vista is for PC, Android is an OS for phone. The latest
Android version is Froyo 2.2.1.
I would not say android is better than an iphone because each
has it own pros and cons.
If you buy an Android phone, there is an app called "Market" in
it. When u enter, there are tons of free apps inside for you to
download. The paid version is coming soon to Sg. But there are
always ways to get free paid apps without the need to root your
phone.
A few of the awesome apps that are free are
Google Map, Google Latitude (you get to see where your freinds are
on the map), Voice dialer, Gesture Search, Barcode scanner, Starhub
TV (you get to watch free History channel and National Geographic
if you are starhub user), Ringdroid and more.
Hope this help clarify.
