Someone mentioned earlier that is true "multi-tasking."
In the consumer sense of the word, yes. But multi-tasking is actually a technical concept, not just "can it do more than one thing at a time?"
As someone said up top, no phone is perfect for everyone. If this particular feature is an issue for you, then stick with the piece of technology that works best for you. *shrug* End of story.
There's not a hack for that because it's a limitation of CDMA.
That's the biggest difference. Its not like Verizon won't allow it, it can't be done.
