Ok guys, I skimmed through these post and it seems a lot of you are wanting the ACTUAL 411 about this update, here it goes.
First of all let me explain that this update had NOTHING to do with HTC. THIS WAS ALL SPRINT !!!
2.1 Was master released by HTC, it is then up to all the cell phone providers to Redo the update and add all thier own Software and fixes. This 2.27.651.5 - .6 is exactly that.
as far as .6 goes, all it ACTUALLY does is " fix " the root exploit on the Hero and the EVO, also on the Hero it fixes the Phone dialer/phone call delay issue and an uncommon but still troublesome MMS issue. On the Evo, besides the root exploit being " fixed ", it also addresses a major SD Card issue and a known MMS issue.
THAT'S IT !
thus the OTA version only being 3 Megs.
Now as far as the supposed " Battery Performance Increase " this is not true, it's just based off of how you use you phone ( like it always has been unless you use a custom ROM and/OR power management App )
Now there is a Slight increase in overall speed, but that's just because of the fix to the phone service I mentioned ealier, so it's not using as much Processor speed.
Now I am in personal contact with the guy who came up with the "UNREVOKED " root exploit for 2.1 that was based of the Evo and implemented to the Hero. So if you have any questions, feel free to hit me up on google talk:

Also if you do get this update and want to root, just reflash the 2.27.651.5 update and redo the unrevoked exploit. Then there are custom roms built off of the 2.27.651.6 release that won't unroot your phone.
Also I recommend using an awesome rom like Fresh 2.1.2 and if you want, apply an overclok kernal so you can overclock your phone. I have mine overclocked to 710 Mhz, I DO NOT recommend going any higher as this will freeze your phone.
Well that's it folks. I hope this helps.
