So, since Coderus hasn't yet released his Whatsapp forever-version, Whatsup is currently the only working N9 WHatsapp application, right?

I am happy to "have to" use my N9 again for a while, so since I haven't used any Whatsapp applications in some time just want to ask first.

Should this "reborn" Whatsup version be used or is the old one still more stable? Also, is registration working on both without having to do much extra hoops?

Greatly appreciate that Cepi is also working on his application again
