I just installed GO SMS Pro, then disabled the internal SMS application from the Manage Apps menu. Now, when I slide to the SMS app on the lock screen, GO launches.
I suspect a replacement camera app will work the same, but I'll let you find that out for yourself![]()
I tried this and now I cannot receive MMS messages.
How do you make another SMS app default?
go into the stock SMS app, uncheck the box that makes it the one being used (i forget the exact wording, but it shouldn't be that hard to figure out), then go into handcent, or go, or whatever you use, and check the same, or similar-sounding, box and it should default to that one, then freeze the stock app.
i'd advise you have someone send you a test text before freezing, just to make sure that you're ONLY getting notifications from your selected app, and not anything else.
