I want to connect iphone to a printer via bluetooth, but I don\'t find any class about bluetooth in iPhone 3.0 SDK. Do I need to join \"Made for iPod and Works with iPhone L
Even if you join the MFi/WWi developer program, it's impossible to connect your iPhone to an arbitrary printer. The printer would need to built specifically for iPhone compatibility and incorporate an Apple-specific chip. The program is intended for device manufacturers to build iPod/iPhone specific devices, not for independent developers or device manufacturers with existing bluetooth products.
