This answer applies to R4i Mk2
R4i will charge and control all iPhone models, but as it is ‘Made for iPod’ compliant (rather than iPhone compliant) you may hear mobile phone interference when ‘flight mode’ is not selected. It is worth noting that this interference usually only occurs when your iPhone is not receiving a 3G signal and is in regular GSM or EDGE mode. With a good 3G signal interference between iPhone models and R4i will be negligible.
To use the latest iPhone models with R4i you will need a 30 pin to Lightning adaptor (available directly from Apple) and the Lightning Adapter Support (LAS) available through Proporta.
