Is it possible to have the radio switch between WCDMA Preferred mode, GSM mode, and WCDMA only, for example, without the radio switching off and on again? The radio completely loses signal during the, which isn't ideal.
It seems like it must be possible theoretically, as the phone doesn't lose signal when in WCDMA preferred mode, when it downgrades to GSM because of poor signal.
If it matters, I'm using an HTC Desire Z running Cyanogen 10.1 (Android 4.2 based). This problem also occurred on all previous versions of CM that I've tried, and on stock JellyBean 4.2.
This also occurs on a Nexus 4 on JellyBean 4.2.
