Are you a proud owner of a Lenovo IdeaPad K1 and have been longing for some ICS love? Fret not, as Lenovo has officially outed their ICS upgrade for their venerable Android tablet. There’s a catch though – the ICS upgrade is a basic, vanilla OS, which means if you’ve fallen in love with Lenovo’s customizations such as the launcher, pre-installed Apps and their own appstore, then you might not want to go through with the upgrade. You’ll also be deleting all the data on the slate as well, so think it over carefully. If you have decided to make the jump to ICS, you can head on over here for the full install guide.
