For this guide, I'll be using my setup to explain how this is done. Your mileage may vary because you and I may not have the same equipment, but the concept should be pretty much the same nonetheless.

Laptop: Dell Inspiron E1505 with Express Card slot
OS: Windows XP Pro w/ SP2
Data Card: Merlin XU870 HSDPA ExpressCard/34
Bluetooth: Dell Wireless 355 Bluetooth 2.0 with EDR

IT: Nokia 770 w/ OS2006

------------------------------
First let's start with a little background. I live in the US, using a HSDPA card with TMobile surfing on an EDGE network. How is it? Horrible, but tolerable. I bought this card not knowing fully that there is no HSDPA service (yet) with TMobile over here in these parts. I assumed that whatever TMobile europe had was over here in the states at the same time. Nuh uh. Not the case. Learned that the hard way. Although TMobile has mentioned that by the 4th quarter of '07, HSDPA should be up and running in the major cities in the US. We shall see.

But then again, this data card is among one of the few that is of expresscard architecture that my laptop can use. USB is quite inefficient when i carry the unit under my shoulder on the move with a dongle and unit to hold tight while i run with. So that's my story.

Laptop with expresscard slot, using a hsdpa expresscard, on a US based carrier running on an EDGE backbone currently. Now let's get to the guide.
------------------------------

First, let's set up the data card. Assuming you have installed the proper drivers and software with the unit already, make sure you do not have 'connect on windows startup' (or similar) turned on as default.

Once drivers and software are installed, your card should be detected by windows and your status light should be on stand-by mode.

------------------------------
Now let's set up Bluetooth. Assuming you have installed the proper drivers and software with this piece already, make sure you bond the nokia 770 to the laptop.

** To Bond Nokia 770 to your laptop

Nokia 770:
goto 'Tools' > 'Control Panel' > 'Phone', click 'New'.

Laptop:
go to your software and search for the Nokia 770, type in pairing key, and it should connect. End result screen would look something like this. Also, be sure to turn off 'discoverable' on the laptop side (example), as well as, 'use only specified devices' (or similar; depending on individual software descriptions). (example)


** To set up Nokia 770 connectivity to your laptop

Nokia 770:
goto 'Tools' > 'Control Panel' > 'Connectivity'.
- 'General' Tab, choose 'Connect without asking: [Any Connection]'
- 'Idle times' Tab, set your time idle limitation settings for 'Packet data' (I have an unlimited plan, so I set mines as [unlimited])
- click 'Connections' button > 'New' > 'Next', give your connection a name
- choose 'Connection type: [Packet data]', click 'Next', choose 'GSM/UMTS' [for tmobile, cingular, or gsm carrier; choose 'CDMA' for verizon/sprint], click 'ok'
- Access point name: 'internet3.voicestream.com' [for tmobile users; cingular/verizon/sprint/etc, refer to your sources for the APN (access point name settings)], dial-up number '*99#', user/pass are blank
- Click 'Next' > 'Finished'

Laptop:
open up 'Windows Explorer', goto 'My Bluetooth Places' (or similiar, depending on your software),
- click on 'View My Bluetooth Services', right click on 'My Dial-Up Networking' and goto 'Properties' (example)
- For Modem, select your data card from the drop down menu. (example)
** Important: Be sure your Bluetooth is 'ENABLED'. Although the blue light may be turned on/showing on your laptop dash, you have to enable it in the OS for the connection to take place. (example; the 'disable' button on this same screen actually disables bluetooth from usage)(example)

Nokia 770:
go to your connection icon on the top right of your screen, open the connection to your bluetooth connection.

Congratulations. If you are a data card user, you should now be able to hop online.


** Also, do note, that when you are using your 770 using bluetooth tethering, your laptop cannot use the modem at the same time to do simultaneous surfing. Also, if you go to 'Tools' > 'Connection Manager', from the title bar 'Connection Manager' drop down menu, go to 'Internet Connection' > 'IP address', the 770 is connected directly to tmobile's network directly tunneling through bluetooth through the data card.

As much as I try to VNC into the laptop, I'm just baffled that I cannot do it. On the laptop side, the bluetooth network has an internal IP of 169.254.x.x. I cannot connect via http://169.254.x.x:5800 or 5900.


And for an added bonus, if you use bluetooth to do your surfing, from a full battery charge, you can get 7+ hours of usage from tethering the 770 to your laptop as opposed to using wifi. (Proof)

** Proof image should be noted that prior to that 6:10:35 of usage, I was using the unit to show co-workers certain games and such for about 1.5 hours in offline mode. I have yet to do another test on just how much surfing can be done with the unit straight from a 100% full charge. Also, I was surfing with Opera with images turned off. I was transmitting pure html text as well as using IRC and Pidgin. For 5MB worth of text surfing, that's quite a few pages.
