google play store - How to change the account for Android Market?

I use two Google accounts and add them to . Let's say acc1 and acc2. When I try to buy an app in the Market, it chooses acc1's Checkout account, and I don't see an option to change to acc2. Can I use acc2 to pay this? And I still want acc1 as the main account for other purposes. (i.e. Talk, Mail, contacts)

Answer

As of mid-2011 the Android Market supports multiple accounts.

To add another account... Press menu button – select settings – Accounts and Sync – tap on “Add account” and add your another gmail account. To activate or use another gmail account in the market, open the new market app (v 3.0.26) and select “Accounts”. A list will pop-up showing all your gmail accounts that you’ve added in “Accounts and Sync”. Select the one of your choice and you’re good to go.
