Force 1X over EVDO in Touch Pro2 (or toggle btwn CDMA 2G and 3G)

[Shahriar5252]

Does anyone know why the registry hack for enabling the Mode of Operations in Sprint's 1st generation Touch Pro (wm6.1 stock ROM) does not work for Sprint's Touch Pro2 (wm6.5 stock ROM)?

For Sprint's 1st generation Touch Pro, Mode of Operations menu can be enabled by going to registry\HKLM\SOFTWARE\OEM\PhoneSetting and changing the value of 'HiddenModeOperationPage' from 1 to 0. Then, in Comm Manager, you could click Menu, Phone Settings, Services Tab, and scroll down for "Mode of Operations". And you will see "Hybrid", "EVDO only", and "1X Only" as options that you can select. Others even made a mortscript-based toggle switch to toggle quickly between Hybrid and 1X Only modes.

I find the same registry key in Touch pro2 (wm6.5 stock ROM), but changing the value of 'HiddenModeOperationPage' from 1 to 0 still does not bring the mode of operations menu in the Phone settings/CDMA services tab. I checked the registery key to make sure the value was still 0, and it was. But I still cannot get mode of operations menu.

This is needed to save substantial amount of battery if you live or work in an area where EVDO signal is weak and your phone is constantly jumping between weak EVDO and better-signal 1X.

Also use of Sprint's Airave, which only provides 1X, can be enhanced by forcing 1X only mode because you don't want your phone to try to switch to a far away EVDO tower momentarily because of the weak EVDO signal in your place. That would result in dropped calls all the time because sometimes calls come through when you are momentarily connected to the far-away tower.

There are mortscript-based toggle switches that people have made for custom ROMs with wm6.5 (see post#2 here), but I need to get the mode of operations menu to show up in Touch Pro2 first.

I really need this, so if anyone knows how to get it working for Sprint's Touch Pro2, please let me know.
