[citation][nom]g00fysmiley[/nom]so you buy the app on your iphone account... and use your virtual phone... why do i doubt this is anywhere as secure as an actual burner[/citation]
The phone is ID'd by it's IMEI as well on the network. Since that doesn't change (because it's illegal to spoof an IMEI), your "burner" can burn you up pretty quickly in a real need situation.
Therefore, this is just a toy app for bored kids. The only thing this burns is your parent's money, and you will get some burn for that.
