Possible to run 4G radio only?

[tokuzumi]

I have not found a way to turn off the voice radio, and use the 4G only.

I noticed you said you were having battery issues when leaving the phone in 3G mode. HTC Sense-based phones have an option to disable "Always on mobile data". It turns your data connection when the phone is in standby. I still get gmail notifications right on time. I haven't found a con to using it yet. We find it under menu, settings, wireless and networks, mobile networks. If you don't have a setting for that in your settings menu, get JuiceDefender from the market. It's free (you can upgrade to UltimateJuice if you want full functionality), and will shut off your EvDo/3G radio when the phone is in standby. It turns it on for 1 minute every 15 minutes. I used it with good success when I was using the CM6 nightlies.

I'm not sure what kind of user you are with your phone. If you are someone who never turns the phone off, there's not much you can do.

Thanks tokuzumi!

It doesn't look like us Samsung users get that setting in Mobile Networks... I'll check out JuiceDefender!

This is my first Android phone, so I'm trolling the EVO and Samsung forums now just to get a good handle on what we can and can't control.

Reply MUCH appreciated!
