    I don't have my Evo yet so I can't and won't say this works 100% but from what I've read and what people have told me this seems to fix the problem so you won't have to do the GSM/CDMA trick anymore. Many have told me that you have to manually update this by going into -> Menu > Settings > System Updates > Update PRL

    Let me know how it works out for you.

    This might actually work. I couldn't activate my evo until after the weekend, and a pro update happened then. And when I went to do the cdma trick, my settings were already correct. Not sure those two things are linked, but maybe.

    You'll know it worked if bring up the dialer. Dial *#*#4636#*#* (Do not press "Call"). After a second, it should bring up the "Testing" menu.
    Go into Phone Information, press MENU, and tap "select radio band." You should experience a Force Close, don't panic, this was supposed to happen. Scrolling down shows that the preferred network type is CDMA (prl) or CDMA (only).


    Also your TWS (Time Without Signal) should be pretty low if you are in good coverage and by low I mean around 10% (again if your in good coverage at all times). You can check the TWS by going into Settings> About Phone> Battery> Battery Use> Cell Standby. Make sure your phone has been off the charger for about an hour.

    Your welcome :D

    Does this service allow the EVO to be used on Verizon's network?

    So I downloaded an app called "Network" which is the same as dialing those random numbers. I click "CDA AUTO" and then I check back a few hours later and it's back to GSM. What gives?

    From what I've read you can use the Network app to change this. As for the problem with it changing back, if your using the method where you dial the numbers every time is force closes the settings for the network get set back to default, thats why it goes back to GSM.

    I'm not sure if the Network app would do the same if you go back in to check the settings. Also if you reboot your phone you have to change it again because this trick does not stick after a reboot.

    I did a hard reset on my device the other day and after it, it defaulted to CDMA.....Originally it was on GSM.
