A few days ago, I updated my lg optimus m via software update by usb on my pc. wife has same phone as well. with the recent metro pcs 3g expansion, my updated phone has the 2.2.2 os, wife's, the 2.2.1 (not updated). her's gets constant 3g, even in our house where we have wi-fi! when she turns off wi-fi in the settings/wireless & networks, she has 3g. I dont have 3g, except very intermittently. when i turn off wi-fi in the settings menu, i have 1x. Is this possible due to the recent update i installed in my phone?
