Hey great to here you got an inverted version finally up and running...
both Talk.apk and Talk2.apk would show as Talk in apps, so my guess is that Talk is listed first so by default your D3 sees it as the one installed....but like you said if you got it to work, it works so no worries...

I did see that the D3 update you mentioned did have the Talk2 and that it was indeed deodexed, so kejar's that to posted may have just been a more up to date version of Talk
