How do I Bluetooth tether an android with data (using pdanet+) to an iPhone 4 w/o data (jail broken)

I have an android phone with data and an app called pdanet+. However, my phone isn't compatible with the wifi hotspot feature of the app. Therefore, I decided to use the Bluetooth internet feature of planet+, but it won't show up on my iPhone. Does anyone know what jailbreak tweak I can get to be able to make the connection between the phones?
