BestBuy(and other) upgrade checkers say I'm fully eligible now, Sprint.com says...

[Chuck_IV]

So I posted this at XDA but wanted to see what people thought here...

On Sprint's website I'm only eligible for the $75 upgrade now and on 9/1/2011 I am eligble for the full upgrade. BUT, BestBuy.com(RadioShack.com, Amazon.com...) upgrade checker says I'm fully eligible as of this past June 1st. Doesn't the info that these upgrade checkers display come directly from Sprint anyway?

I have a preorder at my Best Buy. Should I worry about what the Sprint website says over what Best Buy's upgrade checker says?

I need to call Sprint tomorrow and change my plan from SERO to SERO-P before Friday, so I'm wondering if I should just let the upgrade thing go as is and be ok or try to get them to give me an early update.

FYI, My 2 yr contract is up 11/1/2011.

Thoughts?

Thanx
