Sounds bonkers, but it is actually quite handy.
So i have a Nokia E71 and have been using mobile internet for years, way back when the first GSM phones came out, when you used dialup networking with *99# for it to create a GRPS connection, and its come a small way since that.
From the early days of Dialup over GSM at 9600BPS to Current day with 3.5G (I can’t believe its broadband) there has been one failing with all connectivity, the 3G modem, or connecting your phone to your laptop.
Bluetooth was finicky and usually slow, unless both devices are Bluetooth EDR Enabled, even then it can be a pain to get the two devices to pair etc.
USB Cables are a joke as well, for one, they rarely charge the device at the same time, which i think they should do, plus you had to carry around another cable with you.
Dedicated 3g Modems are another disaster, why is it that the providers have to release the CRAPPIEST connection software ever, Vodafone, T-Mobile, Orange, Three … I’m looking at you … I mean could you not have released nice minimalistic software that doesn’t have massive company logos emblazoned all over it.
Enter Joikuspot, which i found after getting completely racked off with the Vodafone software + my Huawei modem and I was after starting in Germany working, I’ve used various incarnations of 3g offerings from various different networks and they’re all rubbish. In fact I had a better experience using the Huawei modem on Ubuntu, which is saying something.
The idea with Joikuspot is simple, your have a Series 60 mobile that has Wi-Fi and 3g, so you download this Application and it turns your phone into a Wi-Fi hotspot, simple ? Well yes it is that simple.
Download the application from:
You can enable encryption (just like you do with a normal Wi-Fi router)
Set a Network name
Then enable sharing ..
Search for the connection on your laptop, enter your network key and thats it.
More than one person can also use it.
The other option is to carry around a fullblown
Linksys WRT54G3G
Which works just as well but I think carrying around a phone that does pretty much the same thing is much better.
It comes in two flavours, Light and Premium, Light being free and only allowing only port 80 and Premium allowing all traffic. The Premium version was 19 Euros and well worth it.
Of course you could always run OpenVPN on port 80 on your home network and *ahem* not have to pay for the Premium version at all, but I think its worth purchasing 
The Licensing is quite simple too, it sticks to your SIM and not your Phone, so if you get a new phone then its no problem changing over !
