I have been having issues connecting my iphone to my PC collection and I have posted a few topics and followed the directions people have given me with no luck and I noticed looking at a few other topics that people are fixing their issues because of firmware what kinda of changes are they making to the firmware cause this to be my last option to get my collection to my phone and i have no idea what that is.

If you are using a wifi connection with the software, I suggest reseting your router. This will give you a new IP address, which you can use to enter into your settings on the iDevice. I had this problem myself I did what I suggested to you and it worked.

I have a wireless router. I am also using windows vista. I have my iphone set up with the wireless connection not the 3G. Everything is up to date as well.  Mighty Mike I will try resetting my router and see if that helps.

Just like many of you, I too was having connection issues between my iPhone/iPad and my PC running DVDP.  After scouring the forums and trying all the suggestions I could find, I decided to upgrade my router.  I had a Buffalo WZR2-G300N that was only a couple years old, but I could not figure out how to turn on multi-casting.  I went out and bought a Cisco/Linksys E4200.  All I had to do was enter the required port into port forwarding section of the router and after that it was able to sync successfully to both devices.  I am still not totally certain that it was strictly a multi-casting issue, or whether or not there was something else that my old router was unable to do, but either way it now works as advertised.
