I don't have that option!!!Under settings,applications, then there should be a option for setting your defult
Try going to menu>settings>applications>manage applications> select the All tab, scroll down to Messaging and then click Clear Defaults. Then go to your contacts and select any contact with a phone number, touch the little envelop and it should bring up a choice of which messaging program you want to use. FIRST, touch the check box at the Use by default and then select Chomp. That should make it always use that sms app thereafter.
This worked!! But will that keep chomp as my default for all text or will I have to do this when ever i want to text someone new?What about just looking up a contact and clicking the envelop icon beside their phone number? Does it pop up a dialog box asking you to choose which app to message with?
