Yikes, not to sound sarcastic - but it sounds like someone didn't do their homework!
Without hacking the iPhone OS, you can't install ANY software. Hacking is certainly an option, but as stated, you void your warranty. You will also lose any customization you may have done with each subsequent update from Apple - this last one was particularly harsh on some users, causing serious issues with the devices. It also seems that with each update, the people making the hack-ware are having a more and more difficult time breaking into the system. So, short of the controversial use of web-based apps, there's not much else in the way of options.
Blue Tooth? On the iPhone, it's only for telephone conversations. The required serial bluetooth profile is lacking at this point. There is also no A2DP profile, so without a stereo "dongle", you won't be listening to your music wirelessly, either.
These are all well documented issues with this device, so I hope you were aware when you bought it. It's missing some other key features, too - but it's all WELL documented - cut/paste, file management, Flash implementation, just to name some of the biggies. Still, even with these limitations, most of us still love our iPhones. Myself included.

Assuming you have SSH installed on the phone and you are on a Mac, you can use a program such as Fugu or CyberDuck to copy the files over to the iPhone. If you are using Windows you will need to use WinSCP to copy over the files.
You will have to get the IP address of your iPhone when connected to a WiFi point and use that. If you are using the 1.1.1 firmware and haven't changed the root password, the username will be 'root' and the password will be 'alpine' without the '.
