We do like it when our new members use the search function. There are LOTS of threads about IOS6!
But, that said, welcome to the forums, and yes, if you have an iPad2 or iPad3, you will get IOS6 for free next week. Go to Settings > General > Software Update.
If you have an iPad1, then no dice. 5.1.1 is likely to be the last version of IOS for the original devices.
