I have this app and just about every number comes up as unlisted, >95%. It also laggs showing the caller id. I have an evo so it's not the phone. I used to user another caller ID app on my hero, Who Called? by XLY Labs, and it worked better then Super Caller ID.
I was wondering why Super Caller ID it rated so high and noticed that they only have 10-50k dowloads but have over 3000 ratings. This is abnormally hight rate of raitings to downloads so I assume the dev is boosting as other apps that have that number of DLs only have a few hundred reviews.
If anyone knows of a good Caller ID app please let me know. I'm still looking.
