Zinio is jumping on the Kindle Fire bandwagon today. Its newest Android app is now available in the Amazon Appstore, just in time for you to install it on your KF.

Zinio is promising a $25 credit to any new registration, and what’s even better is that the offer is open to all, not just the Kindle Fire owners.  If you set up a new account from your PC, iPad, smartphone, or other Android gadget you’ll also get the freebie. You can even install it on the HP TouchPad.

The credit is good for any of the 5,000+ magazines sold by Zinio, and it won’t expire until March 2012.
