Hi I just recently bought a Blackberry Curve 8320. I am a mac user and i hace synced my blackberry with entourage using the pocket mac application which comes bundled with the blackberry device. Once after i synced it with my mac i tried to install some third party applications on it from a windows pc but it refused to do so. my question is that after i have synced the device with a mac can i still use a windows pc or laptop to add third party applications on my device?

Try searching and posting int he MAC section. Might get a better response from the MAC users there.

There shouldn't be any issues with syncing between two machine. I sync my 8830 between both mac and pc pretty much every day. Never had any issues installing applications either. Does it give you any specific error messages when you try to install apps?

Same here, no problem between machines. I use Missing Sync though.

yes it says application can not be installed.
