Very interesting.
I'm having a similar problem with Vodafone N73 atm.
I got a free n73 from CarPhoneWarehouse for helping them out on a project and it is completely debranded and de-locked. I can install any themes, apps, games, etc that I want.
Now, I had the opportunity to upgrade on my Vodafone account to a n73 for �23.00 - Great, means the wife can use the debranded one and I'll use the "locked" version. Shouldn't be a problem.
However, I was completely and utterly wrong.
Having spent 25 minutes argueing with business support AND their handset division, they have now told me that it isn't a problem with the "Sim Locking" but a problem with the certification, and I need to address this with Nokia.
They did not seem to understand that due to their SIM LOCK process, and the software, it stops me from making Themes via the official Nokia SDK and loading them onto the phone. When trying to install it, it says : Unable to Install - Certificate not Authorised.
Vodafone then told me, this is to stop copyrighted material being used illegally and I would not experience this problem should I purchase a Theme from Vodafone, as they have paid all copyright. I then tried to explain to them that I OWN the copyright, as I made the theme.
This is when they claimed I didnt know what I was talking about and I can either pay �25 to have it unlocked, OR, send the phone back.
So, the question ultimately is....
Will Dolphs Suggestion work? and if I do Unlock it and pay their "RANSOM!", will this resolve the problems.
Thanks
