I'm running Chatter 3.02+ and installed the Sprint 700P MR last week and have installed some other programs within Chatter since, but today it stopped working. I've tried reseting (soft) to no avail. I'm able to download the attachment, but when I try to add it to my applications, it gives me the error:

Error: The data was
not accepted.

Luckily I have Versamail set up and I'm able to install things fine with it. I'm running Vista so I can't hotsynch new apps, although I guess I could transfer them to my card and install them that way, but this is just easier and doesn't require me to be at home to do it...
