Using the very useful threads here on AC, I've recently rooted and loaded the "aospMod | AOSP 2.2.1 (Froyo) [12/10/2010]" ROM onto a Hero based upon a suggestion by chefkeyser in another thread. I've worked through most issues, but wife noticed that the 'voicemail' app was missing. After doing a bit of searching on the intertubes, I've found flashable zips of the .apk attached to an Evo thread or in a Hero thread discussing a Cyanogen ROM. My question is might I be able use one or the other of these zips to flash or is the Sprint VVM apk specific to the hardware (ie. works only on the Evo) or taylored to a particular ROM (ie. works only with Cyanogen)? If neither of these will work, does anyone have a flashable VVM for a Hero running the Froyo ROM that I listed above? Thanks for any help here.
