ToySoft released a beta of their full screen PictureID software for the BlackBerry Storm this week. The current product page already says the Storm is compatible but there is a different link for the beta found on the forums. (OTA beta link)
The app is available for $9.95 with a trial available from what I can tell. The Storm 9500/9530 requires OS 4.7.075+ to work and the app will not work if the BlackBerry is locked.
