The best programming tool for Mobile Applications?

[truthserum]

Java, Delphi...any others? that can write Symbian or similar OS based Applications for MOBILE PHONES?

 

[dequadin]

Tool (as in IDE) or language?

There's Eclipse for J2ME & the Android SDK
There's Visual Studio (.NET Compact Framework) for Windows Mobile?

Not sure about iPhone...

I don't really get what you are asking

Okay I actually need a developer who can create a mobile application from a current VOIP that was originally written in Delphi...
It is a chat program that will have live video streaming but using a codec that will never lag most cellphone OS's.

Investigate your licensing, or rather certificate issues as well... java verified is an incredibly expensive process if you are expecting a large range of cell handset types.

Otherwise go for symbian but that rules out quite a few handsets and also requires customising with each handset SDK. SA, at least affluent SA is largely nokia, SE and samsung. SE and Samsung are both releasing a lot of symbian based + a few WMobile. Almost all current Nokia's are S60.

Symbian is dev'd in C++ with relevant SDKs
Java apps are obviously J2ME with various CLDC's and JSR revisions.
