Yep, I never managed to find anything (software wise) for unlocking Motorolas. I ended up getting mine unlocked by the telco, who did it for free but as it was Orange France I ended up spending a fortune on call charges to call them from the UK to get the 'free' code
Now, I get my phone and all my calls paid for by my company, which is nice, but means that they get to choose which model I use and who I'm with.
