I've seen the gdsms example been discussed but can't find it in the sdk's for 9210, 7650 nor on forum nokia web site. Can somebody tell me how to find this example or an working sms example on the 7650/9210?
You can find GDSMS in Forum Nokia's Symbian/Downloads section under the name SMS_sending_application1_2.zip. This is for 9200 series Communicators.
Unfortunately it is not currently possible to do the same example for Nokia 7650. These APIs are not included in Series 60 SDK. However, we are planning on providing a wrapper that includes SMS funtionalities.
