I am devloping a mobile app that access SMS I know if its doable in andriod if I am using GWT and in Iphone if I am using objective c. My Question is I want to use some framework that genrates native apps (for iOS and andriod) like titanium appaccerator jQuery Mobile ... etc can some one tell me if I can access SMS on the mobile devices from the app wrttien using such tools?
On iOS you cannot access the user's SMS data from an app (at least not without jailbreaking) no matter what tool you use to create it. You can use the MFMessageComposeViewController to compose an SMS, but the user needs to interact with the view to actually send it - you cannot send an SMS without user interaction.
I can't help with Android I'm afraid.
