There is a new program out called quakk. You can check it out
here.
I tried it out and it did not work worth a crap, but it is always possible that it is because of the rom that I am running. Maybe someone with a 6.1 rom could try it out.
I am missing twikini and am thinking about shelling out the cash because even though I really like pocketwit's layout it just does not run as smoothly.
