Who sampled who? Kumi Vs. Blackberry phone?

[catcher_inthelight]

So I've actually known this for quite a while but since I don't actually OWN a Blackberry I didn't know the name of the Ring tone! lol!
Anyways right about the same time a snipet of Kumi's "Just the way you are" preview leaked, I was at the eye doctor's with my dad because he was getting lasecks (spelling)?
Anyways this much MUCH older caucasian lady's phone rang and I immediately perked up because I was like OMMFG! YOUR a KUMI FAN!? And she was like... I'm sorry dear Who is that?
And I was like.....but.....you have a piece of her song AS YOUR RING TONE! Needless to say she didn't know what it was it was set to automatic so that was useless.....Flash forward to WAY after June 5th 2010!
WAAAAY After the song was released I was in ROSS with my Boyfriend of all places and heard it AGAIN!
It was on this Black ladies Blackberry! Luckily her and her son was kind enough to scroll through ALL the ringtones to find what is was called because I told them I HAD TO KNOW.
So anyways the ringtone is called BB Grooves_interlude and you can hear it in Kumi's "Just the way you are" song! So my question is.....who sampled who? Someone please help! I must know!

BTW here's a link so you can here it! ^_^*
