I too got the Photon 4G from BestBuy for $99 on an upgrade. I highly doubt the Photon will drop below $99 before the end of the year.
You'll love this.
I had a Day 1 Evo 4G finally crap out and was getting a replacement. Because it was out of the 1 yr warranty, TEP kicked in, so it was $100 for a replacement. For a refurb! Now, I could just as easily bought a brand new one from Sprint for $99 if I weren't already a customer (for 13 years!).
So, I called Best Buy. THEY had the ability to upgrade me (my year was up and I'm Gold) to a new Evo 4G for $99.
But...they had the Photon and I thought 'what the heck'. I LOVED my Evo BTW.
The Photon has MUCH better hardware...the volume can actually be heard...and the display looks better unless I'm getting anal about the technology of it and looking at it while 6 inches from my face...at an angle...in sunlight (you get the idea).
I go home...happy as a clam. A week later I read the post about it dropping to $99 during that sale.
I go back to Best Buy, tell them about it, and they immediately credit me not only for the $100 but gave back the difference on the tax as well.
Oh....one other thing...I cancelled TEP because I read all the fine print on it and BB's Black Glove. Black Glove is VERY slightly more expensive monthly, but you can pre-pay and get it for less than TEP, plus it's moveable to your next phone at no charge. AND, they give you a loaner if they don't have your phone in stock (Sprint doesn't) PLUS, it's highly unlikely that you'll get a refurb because BB doesn't stock them at all. IF they can't get your phone in a couple of days, they give you a brand new one, off the shelf.
All in all....my BB experience was excellent.
And the MoPho? After nearly 2 months of ownership, the ONLY problem I have seen/had is the issue with the naming conventions for SD Card (where they actually call the internal partition 'SD Card' and not only do apps not see it for backups/music/etc, it can actually eat whatever is really on your removeable SD Card and make your shortcuts to apps disappear from your home screens).
