Can an iPhone be updated to UMA with an iOS update or is this feature in the hardware/chipset? I've been looking for a definite answer and haven't seen one.
UMA is a T mobile feature where calls are made and received over wifi. I had it with my blackberry and loved it when traveling especially out of country. It was just like being in my office.
