I have been after a solution to use the to do list in iCal on my Mac @ home and the MobileMe Calendar web page while at work & away from home AND have it sync OTA with my iPhone. There hasn't been a solution that I have found for this until now! I have tried Things and OmniFocus, but in my opionion they are both too bloated for my needs. I want a simple todo list with due dates, notes, priorities and URLs, that I can use on desktops as well as mobile. The iCal / MobileMe to do list is perfect for this, but until now there hasn't been a way to keep the same todo list on my iPhone and keep it in sync everywhere. I now have a solution. Appigo recently launched a beta of their iCal Sync app for OSX. I downloaded & installed this to my Mac at home, and downloaded their iPhone Todo app. Great syncing between iCal and iPhone over my home Wifi network. Then, I thought, what is to stop me using this over the internet when I'm not at home? So I setup a domain with no-ip.org, which allows you to point a domain name at your home DSL router IP address and have it forward traffic to your home computer. Using a DNS solution in this way means you can dynamically update the domain name to change when your router public IP address changes (unless you have a static IP assigned with your ISP). So, anyway, I set this up to point at my router's public IP address, then configured my home router to forward a specific TCP port to my Mac. So when traffic arrives at the router from the internet destined for this specific port, the router forwards it to the Mac. I configured the Appigo iCal sync app to listen on a static port (the same one I configured on the router) and ensured both my Mac and router firewalls were set to permit this traffic. So now, with MobileMe set to sync automatically, I can add/edit/delete a todo on my iPhone when I'm away from my home wifi network and it instantly syncs with iCal on my Mac at home, then that gets propogated almost instantly to MobileMe. Also it means a change to the todo list on my Mac or on the MobileMe Calendar web page will also almost instantly get propgated to my iPhone (next timne the Todo app syncs). Brilliant! The perfect solution for me, and only costing the price of the Appigo todo iPhone app! If anyone would like more detail on how this was all done, let me know and I can go into more detail. Just need to find something similar for note syncing now, and I'll be sorted.
