I have been around phones for a little while and I have NEVER heard/seen anyone brick a phone by changing roms, when you get into changing radios and stuff yeah.

Sprint can tell that your rooted just by looking at their system, I called in with a problem before and they said maybe it's because your Evolved rom doesn't have an updated PRL or something else, can't remember exactly, but I was surprised that they could see it, but they did, he was the first to ever say anything about me having a custom rom on the phone, and he was in technical support, he didn't say anything and still tried to troubleshoot the issue.

The point I'm trying to make is yeah they might see that your rooted after they fix the phone, but I have never heard of a rom causing a screen not to work, if you have then please show me so I can be more educated/informed.
