Syncing Tasks to iPhone

I use these guys for calendar & contacts, it has been very reliable. I think it will work for tasks, too. Basic is free, premium is 25/year

it syncs my google calendar tasks to my ipod calendar, but they show up just as calendar events -- I don't use a to-do list as much as plain calendar events, so it works ok for me. Maybe Fliq Tasks will work for you: http://www.markspace.com/products/fliq/tasks/

hmph just found a post from neuvasync, they support tasks for Windows Mobile, Palm Pre & Noika

it does sync the google tasks out of google calendar but I don't see a way you could create a task on iphone and mark it as a task rather than an event on a specific day

I certainly don't have an answer for you, but finding an answer starts with knowing the platform you're on and the application that you'd like to sync with - are you on a PC or a Mac? Are you using Windows Mail, Outlook, Outlook Express, Mail/iCal/Address Book, ThunderBird or some google application?

This was the first hit on a google search, but the reviews/comments seem to be positive...
