Today I have implemented transfers into the SteemPay project. I hope @jacobssmartin and @bobarker don't mind me sending them pennies all morning!
Below is a video, from login to transaction finish, to logout. Currently it does not show transaction history, but you can notice my balance go down, as well as view it on the blockchain here:

Currently the transaction flow goes as follows (all client-side): the wallet will check that username is valid and if it exists, check that amount is less than or equal to total balance AND at a minimum of .001 SBD. If these are okay, it will send the transaction. It also allows you to type capitals now, and it will adjust to lowercase automagically.
The only thing left to implement before android v0.1 release is transaction history! Yay!
