i don't think that i'd call the bugs in 4.0.1 minor, at least not on my device, mostly sticking with 2.3.4 - 1223 for now, but i'm very intrigued by the u-boot in 4.0.1 (/dev/block/nanda), as it still has most of the fastboot bits intact. think i might have a 2.6.36 non-android kernel built too.. still testing tho.
Im being kind about the bugs!!! Its interesting how firmwares adapt to individual machines.
Although periodic slow internet, crashing apps, and other bugs are annoying, I found factory 12/23[original, not 1/12 version] to be unstable with 20+ crashes/restarts in 24 hrs. 12/24[wifi optimizzation] seemed to be the best 2.3.4 for my use.
Can the fastboot be applied to gingerbread?
I am in contact with the closed beta group currently testing the latest firmware and as soon as it hits my machine, I will pass it along. From what i gather, it is coming along nicely and we should have Official 4.0.3 soon.
Not sure of your skill[no offense meant] but devs and tinkerers are needed to optimize this tablet.
As far as the custom kernel, what improvements will it bring?
I own a haipad m7[herotab,dropad] and have seen amazing development using the 126.96.36.199[both honeycomb and ics working]
