I’ve persevered with ZYB but now have to officially give it the thumbs down. It’s just managed to lose over a hundred of my contacts. It failed to upload them during a sync and then deleted them from the handset on the next sync. Fortunately I had a copy of them in Outlook, otherwise they would have been gone forever. I have raised the issue, plus some other bugs I’ve spotted, with ZYB but no one’s bothered to respond. Clearly, losing a customer’s data doesn’t rate highly on the company’s radar!
