it is not out for US yet. I got the apk from a euro version but its not 100%.
For instance, when the magazines are fully zoomed out, it doesnt show, but if you zoom in...even the slightest, the magazine shows. Really annoying and not pleasent to use yet.
I contacted Zinio and they said an official android version is coming soon (they estimated around Xmas to Jan).
Shame too cause its so cool on the Ipad...and I want it for the tab.
Also, depending on what magazine you want, the Kindle app has some magazines/newspapers now.
