I admit I am brand new to the Mac but I was frustrated with trying to get my Sony Erricson k800i to show up in Parallels. I wanted to do two things-- synch my contacts/calendar and use the phone as a broadband modem. I was able to solve the synch problem with a plugin that I found that works great until there is an OS update to support the k800i. The second problem seemed unsolvable because I kept trying to install the Sony Connection software in Parallels XP (its not Mac compatible) but I never got anywhere because I got the dreaded "another device is interfering message" even with the new beta. Turns out I didn't need to do this because when I got the bright idea to just to try hooking the USB cable up to the phone and putting the phone in "Phone mode." The built in Ethernet port showed up in the Mac OS networking preferences and I just filled around a bit and it works fine. I get about 45k/sec transfer which I think is about equivalent to a 300kb connection (excuse my bad measures) which is about an ISDN speed which is what I think it is supposed to be. Anyway, I was impressed with how well the Mac setup the network connections without me having to do anything and maybe my experience will help somebody struggling to hook up the phone.
