Sorry, but I honestly think that if more people tried and posted work arounds, carriers would not be able to to submit us to whatever is more profitable, instead of what is better to us, their costumers. After all they are providing a service and they should keep costumer service in mind.

I tired of reading awesome reviews of upcoming phones with inovating features, just to find out that when it comes to the market the carriers had cut the capabilities, because they can force their costumers to pay for a similar service, that these capabilities would provide for free and most of the times simpler.
I think that this behavior is a major hold back on mobile technology. For that reason I support any kind of mod or hacking, as long as it benefits the end user.
