Yes, it's true, you can surf internet, make phone calls, and send SMS by connecting jailbroken iPod touch/iPad(wifi) with normal bluetooth feature phones by way of Bluetooth.
Because this app depends on bluetooth PAN(for internet tethering) and HFP(for making calls and SMS),
for internet tethering, users should use iPod touch and iPad with iOS 4.3 or later, and the bluetooth mobile phone should support bluetooth PAN profile; for calls and sms, the bluetooth mobile phone should support HFP profile, which is supported by major bluetooth mobile phones.
Notice: This is only a test version, and is primarily used for testing the usability of the software on Bluetooth mobile phones and can't be used as a product.
Before install iBtPhone release version, you should uninstall iBtPhoneTest at first!
There are some important points:
1. this tweak is based on apple native bluetooth stack, so it could not work with other 3rd party bluetooth tweak.
2. if you connect bluetooth phone before, and you can't connect now, you could forget pairing in ios setting, then try again.
