PocketCloud seems to be available only from the market place. I have only found the old 1.0 version using APKtor. Where did you get the apk?
I have moved on and tried
Xtralogic first and then
Remote RDP. I am very happy with the latter. Especially as it supports touch enabled applications like Microsoft Office on Windows 7.
The only drawback with RDP clients are the Android limitations on using Ctrl-Key combinations and the right mouse button with an USB mouse and keyboard. Does PocketCloud get around this?
