For those of you who are having trouble connecting your behold to a windows XP machine, you need to do this:
Download the samsung software, update the software plug in the phone.
Now if your like me, you plugged in the phone before doing the updates thinking it would coordinate with the software and work anyway, not the case. You will notice when you plug in the phone, it knows what phone you have but won't update the drivers. In order to correct this issue, you need to go into the device manager (start -> administrative tools -> computer management -> device manager || right-click my computer -> device manager || right click my computer -> manage -> device manager), find your phone in the list (will probably have a yellow caution sign), right click, go to 'update driver'. it will prompt you to search for the driver and you will select "install from specified list". on the next window you will click the "Don't search, i will choose the driver" and hit next. This should bring up your phone in the window. Hit next, it will give you some message about not wanting to do it for verification purposes, ignore that and continue.
That should install the correct driver. If it prompts you with a list of available drivers, you will scroll down to 'modems' and then then you will see your phone in the list and hit next. that will install the driver and then all you have to do is unplug and replug in your phone.
