Since the announcement of the Nokia 7700 on Tuesday, a lot of people have got in touch with the OPL Team to ask when OPL will be available on Series 90 (which powers the 7700). Thanks for the vote of enthusiasm, but in the case of any porting of OPL to platform other than Series 60, the intention is that it will be ported, but not yet.
There are very few members of the OPL team who know Symbian C++ to the extent that is required to translate and bugfix the runtime. We've made the decision to concentrate on one platform at a time, and get that to a 1.00 release before looking at other platforms. So Series 60 (due to volume of units, and the fact that we're approaching 0.30 release in the next week) is what we are working on. Up next would be UIQ. (9210 is already at 1.00) Then we might look at Series 90.
Of course, if you've got the skills, and want to see the runtime on the other platforms, then get in touch!
