I tried the easiest ones, but I guess there is no any yet. The author said as soon as it possible to compile GDSMS with the available 7650SDK, the ported version of the example will be downloadable under Series60 examples. Seems, a lot of developer request it, therefore we work hard on the issue. Please be patient just for a little bit more.

RE: sms/ mms example for 7650 needed
In the meantime, you can try the gdsms on 7650 by replacing the header that refers to gprs (smutset.h and .inl) from the 9210 SDK. It is not a good solution and you should change back to the original smutset.h as soon as the headers will be updated (in a forthcoming SDK). But with this trick you can compile gdsms and it works too.
Also, remember to rename any existing files before replacing so that you can fix your SDK if things go wrong!
