HARDSPL vs New ROM Upgrade

[zuckerj]

I'm sure this is a relatively inane question, but as I'm part of the human race it's nothing out of the ordinary for me to make an inane query.

What exactly is the difference between the ROM upgrade that Verizon just released, and the HardSPL that is being discussed?

And while a technical definition of exactly how both are different will be appreciated, I'm a little more interested in what difference each will have on the overall functionality of my Imagio phone.

Thanks in advance for not making too much fun of me, and for any informative responses.
