thanks for the files. I was able to sideload all of them without any errors (signature, or HTC only) on an LG Quantum with 7720.68 with wp7deploy.exe by Erwin Ried (v.1.6.2)
connect the phone via USB. Have Zune Client open. Drag and drop the xap onto wp7deploy.exe and it will sideload it (it replaces the signature and removes DRM). Note that wp7deploy will not work on WP SDK7.1. you need an earlier version.
btw. do not install attentive phone on any other device than HTC. it will add an item to your settings page and none of the functions will work. there is a way to remove it once you added it.
