The Samsung Galaxy Tab 10.1 has recently received the ICS update, and now its little sibling can join in the family fun. The Galaxy Tab 8.9 WiFi now has an update to ICS available via KIES for those who have chosen to remain stock.
For those who prefer to take full control of their device, XDA Senior Member safariking has put together a package that you can flash via ODIN. The package has been rooted, deodexed, and zipaligned for your pleasure. Safariking also promises that a custom recovery-flashable version will be made available soon.
