Lousy support by samsung and especially vodafone! It's my own fault I bought this tablet. I should have learned from my previous purchase of HTC magic (vodafone), which didn't get any single firmware upgrade. Without the condribution of the custom ROM developers, I would have been stuck to version 1.5 (cupcake).
It's a pity that they don't support their products. It's no use to roll out a really good product, without support. They are pushing people to iOS. At least if you own an apple product, you are sure that you will get updates for a period of time.
