Is there a way to auto backup my phone files to my PC via wifi? I am looking for a way to automatically transfer files in my phone to my PC (Win7) if my phone connects to my home wifi network. Thanks
I'm assuming you mean your photos/music etc. that are stored on the 'sdcard' (even though it may not be an actual SD card). If so there are a number of apps that can do this.

I personally use FolderSync (There is a lite version with some limitations)

Another option is SyncMe Wireless but i've not used it so can't comment on how good it is.
