I use ReQall as it is freely available to me in Canada (where I be from, eh…). I looked in to Jott, but found that it wouldn’t work for me — though that was well over a year ago.

You may also want to check out Dial2Do — my partner here, our illustrious founder and fellow Evernote worshipper, Evan — uses both Dial2Do -and- ReQall (he posted about Dial2Do recently, should still be on the front page of the blog).
