I have a Cosmos 2. It can't detect the phone in either USB Mass Storage mode or USB Modem mode. I read on another thread that it should work in Mass Storage mode, but my phone can't use that mode without a card. I got the cheapest phone I could and didn't get memory card cause that also costs more, because I thought LG would have some kind of "LG Phone Data Transfer" software, but they don't. However Bitpim should have no trouble accessing the internal memory chip that the picture I took with the built-in camera, is stored on now, yet it DOES have a problem, and it won't connect to my LG Cosmos 2 at all. No transfer of contacts, pictures, ringtones, or ANYTHING AT ALL is possible right now.
Please makers of Bitpim, get off your lazy butt and add this phone (LG's best and latest model of non-smart-phone) to the list of phones that Bitpim works with.
And to any hackers out there reading this, I doubt (sadly) that the makers of bitpim have even recently updated the software, so any hackers out there please hack the software and add the Cosmos 2 to the list of phones that Bitpim can detect. You can PM me the download link to the hacked version when you are done making it.
