Even though Adobe Reader on Windows Phone had a recent update, it still did not solve the biggest problem with the app â€“ the inability to forward downloaded PDFs once they are on your device.
XDA-Developer member Bruce_X_Lee has the solution, as long as your device is unlocked.
His XAP, PDF Move, allows users to pin individual PDF files to the Start screen, move them to the Office Hub, where they can be emailed and even to upload them to SkyDrive.
The app also allows batch uploads to SkyDrive, and basically brings features to the PDFs which Microsoft should have built in from the start.
The XAP can be found at XDA-Developers here.
