To put your phone on 3g only, install "Phone Info" from play store. Go into "Phone Information" then scroll down to the " LTE/CDMA/EvDo" (or whatever network mode your phone is currently set to) drop box and select "CDMA auto (PRL)." On GB, I use to keep my phone in 3g only mode because I live in a 3g only area but with ICS, my battery has been fine in 3g/4g mode.
Hope this helps.
