No ability to turn off 4G in ICS?General

    Now that I have ICS the mobile network settings have network mode setting greyed out.

    Previously, I could independently turn on the phone, CDMA and LTE. Tis was handy in England where I could keep the phone off but use the data. I also have problems with the LTE generating noise in audio circuits. The ability to back the data down to CDMA has been very useful -- otherwise I'm left going into airplane mode or shutting down the phone entirely.

    Do others have the same problem with phones with ICS not being able to set the data to be CDMA only, and/or turn the phone off while leaving data on? Any suggestions on how to make solve this?

    I found out about the short cut to turn off 4G LTE. Now it won't turn back on. Well it did sporadically but know when i turn on the lte i lose all data. Not liking ICS.

    I'm having the same problem with the LTE OnOff app. I used it to turn off 4G right after the ICS update since we were in a 3G area. Now that I am in a 4G area, I can't turn 4G back on.

    I tried a solution I saw in reviews of the app: Turn on 4G in the app, power down the phone, and pull the battery. No joy.

    Later: After going through those steps five or ten times, 4G finally came back on.

    The short cut is not reliable.

    There were similar comments in the reviews for the app. I installed it anyway and it's been reliable for me on my Bionic.

    Are you switching between CDMA Auto (PRL) and LTE/CDMA/EvDo?

    Is it possible it's not switching back to LTE because the signal in the area is not strong enough?

    Yes, those are the options I am using.

    Once I finally got 4G service again, it shows 4G = -85dBm.

    Phone Info app works great for me.

    After a day at this setting the battery life is markedly improved.
    Switching between networks constantly was killing the battery.
