[retrodeviant]

The only time I have had to take my phone in, it was because the chrome at the top was flaking badly. The Sprint rep never even looked at what I was running, even though I had already flashed stock and relocked. I asked him if he had ever heard of modded ROMs, and he wrote down the xda website address for me. I think it's better to be safe than sorry, but I kinda got the idea that they don't really care.
