Did you have some issues when you tried to connect my LG GT505 to the PC to bung some music on it? or tried copying a music folder over, it tells you to insert a disc but you had already has a SD disc in it?? LG Phone Problem and Solution
I had this problem some days ago – took half a day messing about – it just doesn’t connect the LG GT505 does it when you choose PC suite or Music options – tried all 3 USB ports on the front on my PC and no luck what so ever – even rang Orange but they just pointed me to LG as usual… but i do have a solution which worked wonders for me and will do hopefully for you too..
Use a USB port on the back of your PC – worked straight away when i done that (i expect it is because its a main USB port on the mother board or something instead of a additional USB port) Hope this resolves your issue as it did for me.

The LG GT505’s unlock code costs me around £20, it was an LG factory unlock code (which relates to the IMEI). LG Phone Problem and Solution
To get to the LG GT505’s unlock menu you have to type:
Enter the unlock code (you only get a certain number of attempts and the code has lots of digits – can’t remember the exact length – so guessing is not an option)
The locks are not affected by firmware flashing. Flashing the firmware will neither lock nor unlock the LG GT505.
