GTD vs. Mobile Phone

I've given up trying to get some lists onto my phone, and have settled for the PDA in stead. That didn't solve all my problems though. Because I don't use outlook, I can't synchronise the tasks with a desktop application. Active Sync will only sync tasks with outlook for some strange reason. I therefore had to find an application that would let me work with tasks on both the desktop and the PDA. Luckily that isn't a hard as finding that kind of application for a mobile phone, and I found a few potential. The one I'm testing at the moment is called Check List Pro, and seem to be what I need for the list part. It doesn't actually synchronise between the desktop and the PDA, but there is a version for each platform, and I can let active sync synchronise the files i've created. It just means that I can't work on both platforms at once, but that doesn't really matter since I mostly need an easy way to carry the lists with me. Now I just need to figure out what i'll do with the tickler file and my reference library...
