I don't think I'm the only one having this problem, but hopefully I'll be able to state it clearly enough that someone can provide me with a solution.
I flashed the 11.26 update (then went back, wiped, flashed 11.19 and then flashed 11.26 over it without wiping to fix notifications), and the MMS app in either configuration doesn't allow me to download photos/videos/etc to my SD card. I long-press the photo/video and instead of the normal list of options that included "Copy attached to SD card", there are only four or five little graphical choices. I tried the copy one, and while it says "Texts copied", I don't really know what it's done, but nothing was downloaded to my SD card. Is this normal, or something only a select few of us are experiencing? And is it fixed in 12.03?
I actually flashed the 11.05 MMS timestamp fix, which just takes you back to an older MMS.apk, and that allowed me to download photos and whatnot, but it doesn't support the theming options present in 11.26, which I really liked.
