I got my 6P space grey 16GB from Target tonight! After I called sprint and they told me I could not cancel my in store pre order I went ahead and just got it from target since my account did still show I had my eligibility since they don't have a tracking number. The bad part is I had to pay $299 again and I won't get my $299 from sprint until the phone shows up in the store.. Which could be another month.
Lesson learned today is never preorder from a Sprint corporate store. I also used the idevicetracker and saw a lot of Target, Best Buy and Apple stores in Southern California with Plus phones. I called each store to verify first and some had them and some ran out. While I was getting my phone one person called to get mine and another guy wanted an AT&T plus but said I'll take any carrier and he told him sorry he only got one shipment for a plus this week and it was the one he was giving to me. I good thing I didn't sit around and went to make it happen.
I advice everyone to use the tracker unless you preordered online and you have a tracking number. If you don't have a tracking number and it's showing your eligible for a phone, get the phone first then cancel after.
