While I was in the process of moving all my apps from my 650 to my 755P, I checked for updates/reports of problems, and I'm glad I did. I found reports that version 2.25 of CEII will cause your 755P to spontaneously reset when the Hotsync cable is plugged in. Softick has
version 2.26 available on their site. As an alternative, you can transfer music with Windows Media Player and
Pocket tunes, and the newest version of
mRing offers an integrated card reader. Both worked just fine on my Treo, and I'm sure there are several other apps with this functionality.
