This is one of the positive things that come from signature campaigns, and one of the only results I like to see, i.e., when the proceeds go toward helping those in low-income areas of the world. People from poor and wealthy countries are basically making the same amount, yet the purchasing power is so much greater where OP lives. I find that uplifting.
And OP, props to you on getting the phone of your dreams! I don't care for smartphones much (though I do own one), but I'm not unaware that they're highly-prized objects to many people--not to mention that some of them are ridiculously expensive. Glad sig campaign earnings helped you get yours.
