I wrote this guide on creating orthorectified imagery using just an iPhone, using a demo on George St, Sydney!
Usually this is easier with drones, but there are a lot of places you can't fly drones. I hope this guide comes in helpful, especially if you're contributing to OpenStreetMap.
I've found you can strap an iPhone to the front of a bicycle and if you go slowly the 3D models/LiDAR point clouds are quite good (it has a 5m range). There are drift issues if you try to complete loops though.
