I'm developing an app for the 3rd world, where they use many older S60 phones, and it would be likely to encounter S60 1st edition (e.g. Nokia 3600, 7650 etc). I also need my app to run on the newer phones with latest S60.
I'm not using fancy stuff, just need a basic UI, plus the Messaging and Inbox APIs, plus maybe others.
What version(s) of the PyS60 SDK should I write for to achieve this, please? e.g. if I write to 1.9.5 I assume that's not going to work on S60 1st Ed phones. That said, I do of course want to use the latest SDK I can if possible.
Or do I need to write against different SDKs for the different S60 versions?
I realise users need to have the right .SIS version for their phone of course.
Where possible I'd like to package the app into a single install file. Anyone know what the earliest S60 version I can do this on please? e.g. possible on S60 1st ed, S60 2nd ed FP 1, etc?
Many thanks for any info!
