Ok, i know this isn't an OS issue, but hey, I have this question....I've seen that there are many adapters for 3G internet technology, but only for laptops, so I need an adapter for a desktop PC. I haven't seen any. The reason why i need it for a PC is because there are no DSL nor dial-up lines where the PC is going to be, but a 3G connection.
Hope u guys can help me to find a PCI adapter or something like that, thanks.
