Answer 2

Ya you can read your incoming message and send also.In your main.m write this code and use three files:CoreTelephony.h,CTMessage.h,CTMessageCenter.h
One problem with this using this way you can't submit your app on app store.
static void callback(CFNotificationCenterRef center, void *observer, NSString* name, const void *object, NSDictionary* info) {
fprintf(stderr, "Notification intercepted: %s\n", [name UTF8String]);
if([name isEqualToString:#"kCTMessageReceivedNotification"] && info)
{
NSNumber* messageType = [info valueForKey:#"kCTMessageTypeKey"];
if([messageType isEqualToNumber:[NSNumber numberWithInt:1]])
{
NSNumber* messageID = [info valueForKey:#"kCTMessageIdKey"];
CTMessageCenter* mc = [CTMessageCenter sharedMessageCenter];
CTMessage* msg = [mc incomingMessageWithId:[messageID intValue]];
NSObject<CTMessageAddress>* phonenumber = [msg sender];
NSString *senderNumber = (NSString*)[phonenumber canonicalFormat];
NSString *sender = (NSString*)[phonenumber encodedString];
CTMessagePart* msgPart = [[msg items] objectAtIndex:0]; //for single-part msgs
NSData *smsData = [msgPart data];
NSString *smsText = [[NSString alloc] initWithData:smsData encoding:NSUTF8StringEncoding];
fprintf(stderr, "SMS Message from %s / %s: \"%s\"\n",[senderNumber UTF8String],[sender UTF8String],[smsText UTF8String]);
}
}
return;
}
int main(int argc, char **argv)
{
NSAutoreleasePool *pool = [[NSAutoreleasePool alloc] init];
id ct = CTTelephonyCenterGetDefault();
CTTelephonyCenterAddObserver(ct, NULL, callback, NULL, NULL, CFNotificationSuspensionBehaviorHold);
// Start the run loop. Now we'll receive notifications.
[[NSRunLoop currentRunLoop] run];
NSLog(#"you are in main thread");
[pool drain];
printf("Unexpectedly back from CFRunLoopRun()!\n");
[pool release];
}
