Ok, so as far as I can tell that this will write out to a prefs file...
Checks here...
./smali/com/vzw/hss/myverizon/rdd/a/d.smali:
const-string v0, "Rooted"
invoke-static {}, Lcom/vzw/hss/myverizon/rdd/a/d;->b()Ljava/lang/String;
move-result-object v2
Writes out to one of their .xml files....
Your guess is as good as mine what they will do with the information... my guess would be to provide the VZW store folks another avenue to see if the device has been tampered with. Perhaps it could be transmitted also. Not worth my time digging further - removed.
