Hi. I have a a HANNSpad SN70T3 that came with Android Ice cream sandwich. I want to know if there is a way to downgrade or maybe even upgrade to Jelly Bean. The reason is I love the Gameloft games but they don't work with Ice cream sandwich and neither does Angry birds. Also other apps don't work when I try them but on the older version of android I have on my phone they do. The tablet didn't have a previous version of android on it which ios why I am asking. Any help would be much appreciated. Thanks
