Thanks symbianyucca. I will move forward with your guideline.
Further more, I found that CPhCltUssd API (which i'm using) is in Symbian S60 3rd Edition FP2 extention pack. Apparenty i have below queries again:
1. Can i use this API in S60 FP1? Like, E71, N95. These are my current test handsets. If not, how to use this API for S60 FP1?
2. Do i need to go for any API partnering program with Nokia or signing? If so how to move forward with that?
3. Will the development certificate with symbian will be sufficiant to run this API in S60 FP1?
Since most of the handsets in the market now have S60 FP1, i need to give a guideline to my customer (a telecom operetor) about the portability of my app, hence i need to know specifically about S60 FP1 as asked above.
I really appreciate your timely response, please guide me ahead.
