Apple announced iPhone 3.1 and iTunes 9 yesterday and part of the upgrade closes off the hack that people used to enable tethering. Basically networks like O2 Ireland have exclusive deals to supply the iPhone and cant be bothered to implement the features of the iPhone. No Visual VoiceMail and no tethering. They don't need to invest the time or money in the infrastructure because they can just pay Apple for exclusive deals and the only people who suffer are the consumers. Monopolies suck.
Still no movies of TV shows in Ireland, that's not O2's fault but it's just another indication that the Irish consumer is being screwed at every turn.
The sooner Vodafone and other networks get the iPhone the sooner we will get iPhone services from O2.
[Update] Looks like there is no support for ringtones either in the Irish iTunes store, or I should say I cant find it where Steve Jobs said it would be, replacing the podcast button on the iPhone iTunes app. Not that I particularly want to download ringtones but I'm sure other people do and I cant understand why they are not allowed here as well.
