Sorry to keep posting this, but if Astrasync does not work on the 9900 I will have to stay with my 9800. I have asked Astrasync if their software will work with OS 7 and they tell me that they are waiting for the simulator software to be released by RIM.

On a side note; we have had a small number of customers report to us that they have install AstraSync with OS 7 and so far not had any issues. While this isn’t an official declaration of support yet, it may prove useful to know this.
