guys, in the graph page of the battery stats, in the bottom my phone says awake with full blue bar underneath it. that means that something is keeping my phone awake and preventing it from deep sleep correct?

is there an app that allows me to choose the type of connection my mobile data is? for example, i want it to stay on 3G only and not on HSPDA since my area doesn't have good coverage. the constant switching of connection type prevents my phone from sleeping and it drains a ton of battery

thanks for all the help.appreciate it
