One of the great things about having remember the milk on the iPhone is portability. You have access to your tasks anywhere with the wonderful official iphone app but it doesn't have tight integration with mobile specific tasks like call or sms or email someone right? Not quite.

The trick is to use custom url schemes. You can add tasks to RTM with the url set as a custom url scheme and it will launch the designated app. With the quick add syntax, it would be like:

call for appointment ^today tel://5559898

text bob !1 sms://5559898
