Acer Iconia A500 tablet gets Honeycomb 3.1 upgrade on 5th July - Mobility feeds
Sounds like it gonna be happening soon and it will have allot of improvements. I'm going to have to remember to unroot. Ive already got all my apps that I froze back and ready.
And on that note if you have used Titanium backup and you froze any system apps you need to thaw them before the update install. That is if you don't want a bunch of force close programs. I did this with the last update and had to do a factory reset.
