i just want to add an update to this topic about the polaroid 7' tablet with IC.
The tablet that comes with IC 4.0 DOES NOT run Google play. its crashes over and over. i have tried everything everyone has mentioned. it works on all the other app markets but does not work with google. IF you can get your polaroid with 4.0 to work with IC and download apps from the google play market, be nice to see a video link on how you achieved it.
