No, Ben, that is a very good question. And the answer, theoretically speaking, could go either way. But, from empirical observation, I can say that Sprint LTE devices appear to be configured to favor much weaker LTE signals over much stronger EV-DO signals.
The process the handset uses to choose LTE or EV-DO is network reselection. On at least some Sprint WiMAX handsets, those reselection parameters are adjustable. I know that Robert got some traction out of decreasing the WiMAX reselection threshold on his Epic 4G Touch and that allowed the handset to acquire and retain WiMAX under weaker signal conditions than originally configured. However, I have yet to find any adjustable LTE reselection parameters buried inside the EVO LTE. No matter, LTE sensitivity seems to be reasonably good, and network reselection takes only a few seconds -- far faster than on WiMAX devices.

One thing I have seen in the ##DATA# menu under the advanced section for the Viper is that the phone is configured to search for LTE first, then EVDO, then 1X. I don't see timers for LTE either, but I do see timers for HRPD and eHRPD. the HRPD is set for 900 and the eHRPD is set for 360.

The ICS Debug lock code is 777468, on every ICS device I've tried it on so far.

Yeah, HTC products typically don't.

But those Samsung owners, well, you gotta keep those yahoos on a short leash.

I was not able to do any extensive testing in KC today, unfortunately, as Sprint has now blocked the LTE site that I had previously used for testing. However, I did encounter an open LTE signal a few miles away from the previously open site. While I did not have time to track down this other site, I was able to do some quick testing. I could fit in only two trials, so these results may not be highly representative. That said, initial testing seems to indicate that an RSRP of ~-120 dBm triggers the reselection timer. If RSRP does not improve above -120 dBm, then reselection causes a drop back to eHRPD/EV-DO.
