This is a major update.
Typical major updates in Android will often leave cache areas stale, dirty, and tangled.
This can inhibit proper operation of update features -- and can even lead to the appearance of old things that were working to be broken now.
For best results, save as much as possible (consider MyBackup Pro, for example), and perform a factory data reset.
If in doubt, ok to wait - but at the first sign of issues, best to give that a go.
Since July 2010, I have never updated without doing a factory data reset.
Others on the forum will attest that this is the way to go.
Not an HTC issue, not a Sprint issue - an Android-wide issue.

At the heart of Android is a thing called the Dalvik Virtual Machine. It's what your apps run under. And it has its own cache. And updates tend to never clear that out.
That's the main issue.
Rooters know to always clear this on rom updates.
Factory data reset is your way to get it done properly if not rooted.
put my phone down at noon it was fully charged it's now 5 30. 10 percent battery left wtf?
) and you would not have a clean install. Question, if I used My Backup Pro to backup applications and data settings on the phone, the do the update, factory reset the phone and then reinstall My Backup Pro and then perform a restore, won't I have a problem because I will be restoring the Data settings for the older OS version?
no need to go through the setup wizard to disable Tell HTC. its avail in the "About Phone" section.
its there in plain site.. some times that's difficult to see.![]()

Whiskey Tango Foxtrot???
I updated with the stock ROM from XDA, updated the radio/pri and rpm, verified that I'm looking at Android 2.3.4, but that option isn't there under "About Phone" for me. Still looks exactly as it did on 2.3.3. Anyone else have this?
If you're ok with using HTC's unlock (and the additional baggage of them being ambiguous about what warranty you're giving up), then yes, take it by all means. If you're thinking of doing it the community way with Revolutionary, I would VERY MUCH ADVISE AGAINST IT. It's possible that another hole may be found, but who knows when.
Edit: On second thought, I'm still not sure I'd take it. The people who have taken it are having an exceedingly hard time (not sure anyone's succeeded yet) in loading a custom recovery and superuser, so while the "bootloader is unlocked", it's of very little use to them, and they're unable to root. At least that's what's going on in a thread or two in the "All Things Root" section. Try here: http://androidforums.com/evo-3d-all...-unlock-wont-s-off-accept-recovery-image.html
are you rooted? is this the reason you did this? if you just used the FOTA then you would have this. i posted screen shots. perhaps the XDA rom removed it?
Does anyone know how to get the dictionary to stop popping up after every word is typed?
As a follow up, something else was screwed up here too, because it wasn't mounting the SD card correctly, saying it may be damaged and I may need to reformat. When I'd try to check the available space in settings, it didn't have any numbers, just said something about "Service started for:" for both internal and SD memory.
NANDroided back to working 2.3.3 from right before when I attempted the update. Going to re-check the MD5 of the file on the card, and try again.
now all they need is an update to fix the call quality, reception, and low volume
