I've had problems with Logten Pro when it comes to sync'ing with a jailbroken iphone. But to be fair to Noah and crew at Coradine, they really went out of their way to try and get it working for me, but it just wouldn't play ball.
10/10 Coradine
5/10 for their mobile version for the iphone.
Apple gave a refund for it, so nothing bad to say about LogTen Pro, but just hope others will tread cautiously if they have a jailbroken iphone. To be fair, nothing lost if it doesn't work as Apple were very good at refunding.
