My SE started overheating in May and wasn't reparable. The genius tried to sell me on a bigger, newer phone, but I declined. Before I walked out he offered me a brand new SE from the stock room for (I think) $270. Just insist that you're interested in nothing but an SE.

Hoping the new one lasts until they come out with a proper replacement. I don't care if the CPU, camera, etc. are 2-3 generations behind. There's nothing I use the phone for that the SE can't handle just fine.
