This was broken when the major update to iap was comitted. ia-lingo7.c created and various iap related files modified. On 4G, 6G and Nano 1/2Gen iPods the remote will function even though the radio won't. Tested on 4G Greyscale, 4G Color, 4G Photo, 4G Mini 1st Gen, 4G Mini 2Gen, Nano 1G, Nano 2G, Video 5G, Video 5.5G Change-Id: Ia74e3d07d9ab5edc6da8eafa96801ede722be331
