I've bought myself a second hand Nokia 7250i that has still 6 months warranty...

The phone is working 100%, but has totally outdated software...

And I wanted the latest software, because it's more stable

I've asked my dealer to upgrade the soft, but asks money for it

So, I was thinking of creating Contact Service, (software way) so HAS to

upgrade the soft for free

But how can we create Contact Source without damaging the hardware?
