I read through the original issue (or saga as BetterMost calls it) and it's unfortunate for everyone involved. From the customer perspective, if you dish out a good amount of $$$ for a high class smartphone, you should be satisfied with it.
I bought 2 EVOs from RS and mine had pretty bad light leakage. However, I contacted HTC directly and got a quick replacement through them. I fully expected that if I replaced it through HTC directly, that I wouldn't be able to deal with RS...not a huge loss in my opinion.
My replacement isn't perfect either. The Menu button led is a different shade of white than the other buttons and there's a VERY small sliver of light leakage under the Home button, but only perceptible in a dark room...I have a polyurethane case anyway so it covers the leak, but nothing will correct the off colored led
Nothing I consider enough to gripe to HTC again about and try to get a replacement though.
From the retail store/Sprint store perspective, the fact that they'd even replace 3 phones is pretty amazing. After a while, I would think they'd just say you know what, get a different phone. Granted that the issues might or might not have been valid for a return, still the number of returns would be questionable after a while.
Logically speaking, why would RS take a phone from the Sprint store back? That's like buying a Toyota from a dealership in a different town and trying to exchange it at a different Toyota dealership. They're both the exact same model, but it's not the one you bought from the original store. If it was a different RS that exchanged it for you and you're going to another RS, then that'd be more plausible.
Anyway, the whole EVO shortage sucks for everyone and if HTC built the phone properly in the first place, none of this would be an issue. Oh well, I hope HTC and Sprint learned a hard lesson.
