I'm technically moderately knowledgable but really new at this so please be gentle.
To put my questions in context, I'm asking about recent GSM capable phone models. If answering requires a specific model assume 6600, which appears to be a pretty generic J2ME platform. If someone wants to suggest something else please chime in.
Is there Nokia generic firmware for most recent phone models? How do I get it?
Will the generic firmware successfully interact with carrier SIM cards?
If there isn't generic firmware, how do you pick carrier firmware for maximum functionality/compatibility?
For phones with memory cards, can you run applications from the card or only access data? I know it might be slow.
