Can I use an iPhone with R2i or R4i?

Both R2i and R4i will charge and control all iPhone models although as they are ‘Made for iPod’ compliant (rather than iPhone compliant) you may see a message on iPhone’s display saying ‘This accessory is not optimized for this iPhone’! This message is to inform you that you might hear typical ‘dit-dit-dit’ TDMA mobile phone interference if ‘flight mode’ is not selected. It is worth noting that this interference usually only occurs when iPhone is not receiving a 3G signal and is in standard GSM or EDGE mode. With 3G enabled and a good 3G signal, interference between all 3G and 4G iPhone models and R2i/R4 will be negligible.
