We inherited a Samsung Galaxy Tab from a friend. It's basically a 7" Samsung Galaxy S. A tablet that's really a full blown phone.
It was released almost 2 years ago with Android 2.2.. The spec is still respectable: 1Ghz uni-processor, a GB of RAM and 2GB of internal app storage.
By the time I got it it had been rooted, and upgraded to a custom Android 2.3. It's been really good.
Yesterday, I found that there is an AOKP Android 4.0 ROM for it ("Build 40"). It may be the end of the road for the Kang Project for Android 4.0 as the links to subsequent builds ("Milestone 6") are all dead.
But everything seems to work: phone, txt, camera, wifi, 3G. It's all good.
So if you have one of these or find one in your possession, at least you know you can get a good ICS ROM for it.
