wcdma (battery issue)

The wacky thing about this hidden utility on my Epic is that when you execute it and choose "Phone Information," the value under "Set preferred network type" is initially "WCDMA preferred." But if you let it sit for about 10 seconds without touching the screen, the displayed value changes to "Unknown."
My bet is that "Unknown" is the real value, and the utility interface is just slow.
Now that I found this, for Sprint, what should it be? Mine is showing Unknown, don't know if it was set there or defaulted as above.
FYI, My phone did the update automatically Saturday night, battery usage has increased 50%. I read, have stopped DRM (as suggested in another thread), and checking this. Something has to be done, I cannot live with
dead phone by 4 pm and I am not what is considered a heavy user. It is rooted.

My battery life, like my social life, could certainly be better.
That's how I came to read this thread.As for what the setting should be, I don't pretend to know. Still researching that. I'm just trying to get the empirical facts right first. I don't think my phone's default setting is "WCDMA preferred," but rather "Unknown."
i just change it to cdma prl or w.e but i havent had much test with it has been charging thru my mac book for the past 5 hours lol
and...
Is anyone else noticing that their "network type" is listed as "CDMA -EvDo rev. 0"? Why the heck am I on Rev 0 and not A?!
Might this also explain our stupidly slow 3g speeds?

You are supposed to be on wcdma as default. It's just wideband cdma, faster data speeds than cdma.
If you toggle airplane mode off/on after reboot, you should notice that it holds at wcdma preferred.

That's not what happens on my phone. I do toggle airplane mode on/off, which prevents the time-without-signal problem. But in the test described in this thread, the utility's display does not stay on "WCDMA preferred." It changes to "Unknown" after about 10 seconds.
I found that no matter what you do, it goes back to WCDMA Preferred and then Unknown. Just change it, back up 1 level and go back and you will see it. Change, leave the menu altogether and reenter it and same thing.
Might kill the battery quicker? I would think so. S/N anyone knows anyone who has a tmobile vibrant my friend gets easily over 13 hours with over half battery left do you think their settings switch to unknown after a while?
Has anyone followed up on this???
Also, can anyone confirm the issues with WCDMA/Unkonwn?? I also heard/read that WCDMA is only in Europe, and not anywhere in the US. can anyone confirm/deny this?
yes, any definitive info on this would be greatly appreciated! if this setting needs to be changed to improve the battery life i'm sure i'm not the only one who wants to get it changed asap.
