3rd ed SDK have SMS Utilities API addon for sending sms via RSocket. It's links to smsu.lib.
That lib is not a part of 2nd ed SDK. It's present in SDK for Symbian 6.0, but then i try to use it on my 3230, app crash on TSmsAddr declaration. So it's no working.
I just whant to make sure what there are no SMSU.LIB aviable for 2nd ed SDK. May be for UIQ? Somebody try to use SMS Utilities or RSock for sms on 2nd ed?
