We have just released the Alpha2 release for DarkWallet.
You can and should use it with bitcoin testnet so you don't risk real money with this alpha software.
This release is aimed at stabilizing the wallet and related infrastructure, also packs a couple of new features.
Thanks a lot to all that have been testing, to everyone who posted issues or pull requests and generally everyone it's been a great week since the last alpha.
Everyone running the wallet should update to the newer version since updates are not automatic at this time.
Enjoy!
looks very promising so far.
if anybody would like to play around a bit here's a testnet address from me so you can ad me to your contacts:
