Why apple didn't support yet the flash player??!!

Do a search and you will find your answers.

Adobe does not offer flash for the iPhone at this time and Apple is not interested in buggy flash lite.

Another reason could be that the iPhone may not be sophisticated enough for the Flash player to operate properly. I doubt this will be on 4.0 OS either.

There are alternatives to the Flash player such as some applications that are designed to run with certain service providers if they have developed a linkup. Such as Quicken Mobile if you are syncing your bank accounts (except EFTs and Bill Pays).

Not sophisticated enough? There are no cell phones that will work with full flash because Adobe has developed full flash for any phone just the bug-ridden flash lite.

Because Flash is a resource hog and websites that use Flash as the only option for navigation don't deserve business anyway. Other than that, I enjoy the absence of Flash because it makes all the annoying ads go away, which seems to be the only thing people are using it for nowadays.
I do believe there are plenty of other options for streaming music to the iphone and Flash would be the WORST method. I am quite happy there is no Flash on the iPhone and if they ever do get it released, I won't install it anyway. It's junk.

4th gen iPhone could have it...The Moto Droid and Nexus One get Flash 10.1 in an upcoming update...of course Nexus has a 1ghz snapdragon processor and iPhone is only 620mhz...

No software update alone like what will be in OS 4.0 will enable flash...it will need to have a faster processor to run bug free...

If Apple plans to include their proprietary processor in iPhone from the acquired Semi chip company they purchased not too long ago then that would be the best chance of 4.0 and the new hardware supporting Full flash.

Only time will tell.....

I hope not. I hope developers start moving toward open source standards.
