I never got 4G service with it; they've not built out in Los Angeles beyond the testing in downtown phase yet. I had to rely on 3G service. The 3G service in virtually every part of Los Angeles that I had an opportunity to test it with was terrible. I routinely averaged 300-500kb/s on 3G. Could get lucky and get 600-700kb/s a fair amount of time. Very rarely saw anything over 1000kb/s. This is a Sprint issue, but since the phone is sold locked to Sprint, it's worht considering. I had a very tough time dealing with this since during my testing I had an AT&T iPhone 4 and a T-Mo Nexus One side-by-side with the EVO and both them routinely got over 1600kb/s and the T-Mo phone actually averaged about 2200kb/s. Sprint has no business calling this phone fast in non-4G areas, and it's insulting they charge $10/mo more for service because you're 4G capable when they should be giving discounts because they can't even deliver competitive 3G speeds.
Call quality was pretty good, but not as much better than my GSM phones as I'd thought it would be based on all the Verizon and Sprint fans comments to that affect out on the web.
EVO 4G phone itself:
Overall I liked the phone. Big bright screen, almost too big. I think the size and weight of this phone is about as large as you can get and still be a comfortable to use handheld/pocket phone/pda thing.
I actually liked the Sense UI on the EVO, even though I did not like the Desire/Sense port Paul made for the Nexus One.
I found battery life acceptable, but I had also ordered a Sideio extended battery (it fit in the stock case).
I found the top button a bit too recessed for my thick fingers...it's much more difficult to turn the thing it is with the top button on my iPhones and Nexus One, simply because it's so recessed.
Sprint swaps the Home and Back hard buttons from the Nexus One, which, given the size and weight of the device, made it difficult for me to use it one handed...I couldn't reach the Home button (far left of device bottom corner) with my thumb without risking losing balance and dropping the phone. Far less of an issue if the Home key were where it is on the N1.
The screen on mine (Hardware version 003 with the Novatec screen) had a very definite pinkish tint to it...bad enough that my friend who isn't a phone geek noticed and commented on it. Others on xda have reported purplish tints on theirs. It bothers some people, doesn't bother others, and the Epson screens supposedly are less pink, but have more muddled grays/blacks.
On my phone, after 13 days of use, the lower left portion of the screen started separating from the body of the phone. This led to light leakage along the bevel which was annoying and disappointing. This is a well documented issue, and I'm not sure if it's been addressed yet.
I did root mine, and could run SU stuff. Now that I hear cyanogen has one and is working his magic on it, I'm almost disappointed that I returned mine.
I don't hate the phone, I was actually saddened that the service was so bad I had to cancel the service, since the I probably could have swapped for a non-pink/non-separating screen phone eventually, but between the screen issues and the poor service I couldn't risk a two year contract.
MAYBE when Sprint rolls out 4G to all of Los Angeles County, and if the hardware issues have been addressed I'll revisit this phone, but I've replace it with the slightly smaller screen (4") Samsung Galaxy S that is much thinner, much lighter, and has a much more gorgeous screen than the EVO 4G, and despite it's having a couple of quirks (no LED flash, weak GPS), it seems a better overall phone.
Good luck to those of you who get one and stick with it. It's not a bad phone, in my opinion, but it's not the phone for me right now.
