In what seems to be tease from the folks at wphonehacker they have tweeted that perhaps the nine dollars for the unlock token from ChevronWP7 is a waste of your money. That maybe just maybe they have a better solution in store for us.
As far as I know the nine dollar Chevron unlock is the only one with Microsoft’s blessing and will not void your warranty. But as I don’t know what wphacker has up their sleeves yet I will not pass judgement on their solution.
This is something I will definitely keep my eye on. Not only to keep you informed as a reader on the site, but also for my personal use for when I get my Nokia Windows Phone in a few months. Stay tuned!!
