How could apple develop things like MMS, vCard support, and even peer-to-peer connections for the iPhone, and yet omit gaping holes like SMS delivery report support? I’m starting to think that SMS delivery reports don’t work in Cupertino.
Edit (July 2009): If you’re interested in getting this feature added to the iPhone OS, please vote for it here: Please Add Delivery Reports to the iPhone.
Update (October 2009): No more silliness with prefixes needed – if you’ve a jailbroken phone, you can now get genuine delivery reports. More info here.
