Wow... 2 posts in 1 day. This is almost unheard of for me! This past weekend I picked up a Samsung Instinct. It's a really cool phone with all kinds of cool little gadgets, but if you just go plugging it in, it won't work as a modem. I've figured out a little way around that.
First, you'll notice that when you plug your phone in using the USB cable, it turns off the phone completely and accesses the SD card in the phone. A simple way around this is to just remove the card. Easy, right? Now you're going to need to change a setting in the phone. You're going to type ##DEBUGMENU# on your keypad (##332846368# for those of you that can't spell). You'll need your MSL next. You can normally get this by asking the person at your local Sprint store very nicely. It'll be a 6 digit number that you'll type in and it'll bring you to a menu. Go to "Toggle NAI" and Toggle modem off. Yes, I said turn it off. Trust me, this is the only way it's going to work. Once you've got all of that done, create a new Dial-up Networking Connection using your Samsung modem. Leave the Username and Password blank and use #777 as your dialup number. That's it! Pretty simple, eh?
I'm still working out some bugs with this. The connection doesn't stay up very long, but it will auto-redial, so it doesn't go down for long. I'm getting about 1.5 Megabit down and 256k up, so it's not blindingly fast, but it works. Hell, as I write this, I'm sitting in at the bar drinking a beer. And yes, I'm using my new Samsung Instinct as a modem to do it.
BEWARE! According to Sprint, even though you have an unlimited data plan, you still have to pay for a PAM plan. I'm not doing this currently as I'm only testing out the functionality. I suggest that if you want to use your Instinct as a modem, you buy a plan with Sprint.
