For those of you running 2.3 with Sense 3.0, correct em if I am wrong but you were already rooted and flashed the ROM instead of taking the OTA update?

To the OP original question, I would not say that the 4G has been abandoned, the issue with rooting is in my limited knowledge not specific to the 4G but the the new HBOOT that is in the OTA and newer devices. As with the original root capability to release though it could take awhile to put this together.

All that being said though the 4G is an amazing phone both stock and rooted, if you can get it for free I would jump at the deal.
