iOS 5 now supports limited drag and drop for email addresses, this makes changing contacts between To, From, CC and BCC much easier. Simply Tap and hold on a contact, the contact will become selected and slightly enlarged, you can now drag between the fields.
Get yourself some Good Vibrations in iOS 5 by creating your own custom vibrations. First you need to turn on Custom Vibrations by going to Settings > General > Accessibility. Now go to Settings > Sounds, at the bottom of the sounds panel you find Vibration Patterns, here you can select one of the examples or create your own.
