Hello,
If you are looking to play go online please check out my Go app. I mentioned it above, it's called 'Goigo' and is an IGS (pandanet) client. It costs £2.50 but you can try it out for up to 24 hours and if you dont like it can refund through the android marketplace.
I have put a good amount of work in to make a Go app that is enjoyable to use, with a nice interface.
Hope you try it out and let me know any feedback.
Thanks,
Dori
