Disconnecting from wifi

[weaselnoze]

I bop in and out of wifi all day every day and use my phone all the time. On the skyrocket, when I leave a wifi zone its takes a long time to realize i've left and to switch to the mobile network. It drives me crazy on this phone bc the voice recognition for sending texts relies on an Internet connection so when I leave the wifi I lose the connection but the phone still shows I have wifi bars for almost 3 minutes.
