I have 2 bb, 7280 works great, just bought a 7290. It will not sync using intellisync. Goes thru the steps then ends without transferring any data. No warning or error msgs come up.The 7280 syncs everytime with no problem. I've gone thru the 7290 settings but cant figure what may be wrong. I also updated the latest bb handheld and desktop software. No change. 1 works, other wont. I can add/remove apps using DM just cant sync. Any suggestions
