Here are my current favorite IFTTT recipes for my phone:
Screenshots to Dropbox - Add my iPhone screenshots to a Dropbox folder
Post Instagram pictures
Voicemail to Soundcloud - Leave a voicemail for IFTTT and post it to Soundcloud as a private track
Siri to Evernote - Create a Reminder list "Evernote". Use Siri to add a new reminder to the "Evernote" list. Append the reminder as a note to an Evernote notebook.
