Foxtel made its broadcasts accessible to iPhone owners (for a fee) back in October, but inspired a lot of complaints because iPhone users couldn't remotely program the iQ using their favourite phone. Now Foxtel has fixed that flaw with a proper iTunes guide application.
I don't have a test iPhone to give the app a spin, but it appears to offer pretty much what you'd expect and want: a full channel guide and the ability to set reminders and remote record options for the iQ. If you test it, give us the good oil in the comments. Foxtel Guide is a free download for iPhone owners. Thanks Grant!
