Wait a minute, I'm not sure I want to lose the follow-me mode. I guess I can keep both firmwares and use the one I want. It turns off easy enough (for those confused, follow-me mode works when you tap the target/locate-me button in Maps and then turns off when you tap the button again -- button "dims" to show it's off.)
I used the unofficial, possible 3G-intended 2.0 firmware yesterday, and now I've snagged the official EDGE firmware ipsw file, as others posted, and I'll use it if I have problems -- I certainly won't use it until I'm sure the iTunes store isn't so bogged down with new 3G activations and old EDGE re-activations with firmware updates I can't get my phone to activate. But I LIKE follow-me mode, and it works fine with tower triangulation in my area. As for power drain, I don't have to leave it on all the time (see above about how to turn it off) only when I want/need it.
Also, a few other points: my EDGE iPhone tower triangulation "pseudo-GPS" is FAR MORE accurate than it used to be. Do we know this has been optimized for EDGE iPhones, or is it only part of the optimization included with 3G iPhones since they use both tower triangulation AND bona fide GPS to locate? Also, I have full location services on EDGE iPhone now with the allegedly 3G iPhone firmware 2.0. Can anyone report EDGE iPhones with official EDGE iPhone firmware 2.0 support location-based services via tower triangulation, or are location-based services only officially supported with 3G iPhones. Finally, on my "early-bird" firmware 2.0 EDGE iPhone the App Store works over EDGE as well as WiFi, while the iTunes Store still works only over WiFi (as I expected is true for 3G iPhone as well). Can anyone confirm the App Store allows for purchase, download and install of apps from the App Store over EDGE with the EDGE iPhone firmware 2.0, or is this feature, in the official firmware, reserved for somewhat faster 3G iPhones?
Yeah, I know: Sooner or later there's going to be a feature I want that forces me to the latest official EDGE iPhone firmware, but for now, though I'm predisposed to get all shaky living on the razor's edge and want everything all official and everything, this works, it works great, I've grabbed the official EDGE iPhone firmware 2.0 release and am hanging onto it for safety's sake, but I'm not going to change anything until I have problems.
Speaking of problems: with yesterday's early firmware on an EDGE iPhone, app crashes, no restarts, no freezes, no problems, period, exclamation point. I'd suggest some problems people are having may just be problems unrelated to early firmware, as people today upgrading to official firmware 2.0 for EDGE iPhones, people who were still at the official 1.xx iPhone firmware, have had a slew of errors and problems not even related to failed activations and failed connections to the iTunes Store for verification.
(One thing, though, when I installed firmware 2.0 yesterday, iTunes did think it was an entirely different iPhone; but it gave me the option of just telling iTunes it was indeed the same phone with the same number, not adding a new phoe, so I selected that and it reactivated, no problem. My iTunes iPhone syncing prefs still show the "old" iPhone, though. Not sure if this is expected behavior because Firmware 2.0 is so different iTunes thinks it's a new phone, or because iTunes now thinks I have a 3G iPhone. Locally only, however, because ATT systems shows I only have two active phones on the same old EDGE iPhone family plan, mine and my wife's, which is same as it ever was.)
UPDATE: Follow-me mode turns itself off when you quit Maps anyway (but not when the phone goes to sleep, you have to turn follow-me off or leave Maps, which is the same as quitting it since iPhone apps may seem like more than one run at a time, but that's just UI, they really don't), so I wouldn't sweat battery life unless you stay in Maps all the time. Also tower triangulation not only is far more accurate, but Maps, at least under the "early" firmware, now also zooms you in to street level so you can really see where you are rather than just dropping a circle around a bunch of streets too zoomed out to label with street names. Used to be you had to manually zoom in deep if it you weren't like on some major 8-lane highway when you tower triangulated.
Last thing, is there a setting so you can give blanket permission to use location, and not have to okay it every time you run a location-based app?

huh.. Really? I haven't got a chance to upgrade to the latest version. But I will agree that this firmware I am on now was intended for 3G iPhones. The maps app has a follow me mode which was made specificly for gps. Good point, ol chap!
