I got an iPad 2 just yesterday from Best Buy and isn't it supposed to come with ios 5 now? If not do apple stores sell iPad 2 with iOS 5?
iOS 5 is a free upgrade.
Once your iPad is connected to iTunes and registered, you will receive notification of the availability of the iOS5 upgrade.
Just proceed with the download and upgrade to iOS5.
Whether or not your iPad has iOS5 depends on when it was manufactured and shipped. It's very possibe that many retailers still have iOS4 on their shelves.
To answer the OP's original questions, yes, Apple Stores sell iPads with iOS 5 installed on them.
You'll have to interface the iPad to your computer to upgrade to iOS 5.x. However, with iOS 5 you will be able to install subsequent iOS updates/upgrades when connected via wireless (i.e., iPad not connected to your computer)
