I run 1Password on Windows XP on my desktop and I am considering installing 1Password on my iPhone 4. I would like to sync the two via wifi without using DropBox so that I can avoid storing data in the Cloud. My sense is that 1Password Pro sync accomplishes this but only with 1Password on Mac OS? Can 1Password Pro on an iPhone sync with 1Password on Windows? If I'm running 1Password on Windows is there any reason I should choose 1Password for iPhone versus 1Password Pro to run on my iPhone?
