I have build 1.0.0.94391081, and I get the trash icon both when looking at individual photos and when selecting one or more photos. Which build do you have? (And which device?)
It's frustrating as I have to click the menu button, then Delete, then OK. I used to just hit Trash icon and that was it. For one-off deletions it's only a little slower - for working through a days worth of shots (or worse, high speed drive shots transferred from my camera).
