I flashed my n9 to the dual boot kernal. I wish i hadn't because jelly bean runs like a dog and i hate using it but no harm done except for all my accounts asking for passwords constantly which unusually fixed itself by doing a restore.

Only problem i'm left with (which seems different than before) is the phone seems to stay connected to 3G when i've been home for hours, even when my wifi connection is in the automatic list. I'm sure it used to default to wifi.

does anyone know what's happened?
