i live in an at&t 4g area but rely mostly on wifi where i usually am. since 4g sucks tons of more battery than 3g, is there a way (or an app) to easily bump down to 3g to conserve power?
AT&T does have LTE only in select cities. They are slowly expanding it. Mean while, they try to pass off HPSA+ as 4g as do many other companies such as sprint and T-mobile. AT&T only has 2 phones that are LTE compatible.
In other words...you are, in a since, running on a 3g+ or a more advanced version of 3g. HPSA+ peak data rates up to 56 Mbit/s in the downlink in theory (28 Mbit/s in existing services) and 22 Mbit/s in the uplink. LTE runs at downlink peak rates of at least 100 Mbit/s, uplink peak rates of at least 50 Mbit/s.
The ITU-R announced in December 2010 that WiMAX and LTE are 4G technologies. Technically they are closer to 3.9G. LTE Advanced is the way to go.
Lessons over for the day...
And which two phones are those?
Regardless of what the network is capable of the phone needs to be able to take advantage of it. Right now the fastest a phone can do is a theoretical 21mbps, but you'll never see that kind of speed.

Maybe some should do a little more reading and less speculating. #1 rule of Android, Google is your friend - use it. We call HSPA+ 4G for a good reason! Because the 3GPP says we can!!!!! Why, because HSPA+ speeds are at the low end of 4G LTE speeds.
learn something new everyday! i've heard way too much false information about at&t's "4g" sucking the life out of batteries.
