Had a chance to install ShadowGo today on my phone.  Took a few hours to download the blockchain, but I finally synced up!  I just sent a small transaction to my phone and it showed up in about 2 minutes:

Want to wait until I see staking working on the phone, but as of now I am highly impressed.  It has been an easy and smooth process.

As far as backing up goes, should I just copy the wallet.dat from the .shadowcoin folder on my phone to somewhere safe?

Thanks again rynomster, you are doing great work.
