Another nice thing to try out: since the iPad version we got was a Wi-Fi only model, it was interesting to see whether it would be possible to share the mobile data connection from my 3G mobile phone with it, in order to go online outside a WLAN network area.
Turns out this is actually quite easy. I bought a JoikuSpot Premium software for my Nokia N900, put in few details, and after launching it up, joined iPad into the newly established local Wi-Fi network. Surfing just fine (with up to c. 500 kbs download speeds in 3G network area). Nice! The only downside is that the battery of N900 runs out really fast if you are all the time running JoikuSpot in it.

…grmpf – it does not work for me – the iPad does see the network (ok – and I didn’t change anything on JoikuSpot – that’s maybe why) connects to it – but I’m not able to surf or do anything with the connection.
