My usb port broke. Bought one of these for battery http://cgi.ebay.com/2-1-EU-Plug-char...#ht_2730wt_905
But I need a good and fast way to transfer large files from PC to N900. SD card isn't an option since my computers SD port doesn't work.( I was able to use it before by connecting my n900 through a USB). I'm not a very techy person so opening it and trying to fix it might cause more problems. I'm out of warranty too.
