I am pretty sure the Architect for the Blackberry OS 4.2 is ARM.

Try doing a search on the web for ARM and you should find that the Blackberry is listed. You may have to dig for actual OS version.

Good luck,

Yes, all BlackBerries I've known use some form of an ARM architecture. RIM jealously hides the internal implementation of their BlackBerry, but they did publicize that the 8700 series used an Intel PXA processor running at a few klicks above 200 Mhz. (Confirmed for 8700). I believe another Intel PXA processor is in at least one model of the GSM Pearl too (not 100% sure).

From the dog-slow BlackBerry 7750 to the rabbit-fast (rumored 600Mhz) upcoming 9000 Series, it's still a variant of an ARM-based CPU one way or another, behind that different vendor name. ARM has become the king of cellphone processors

Nontheless, other BlackBerry models typically use one form of ARM or another, but developers do not write in ARM -- deveopers can only write in Java for BlackBerry.

There's no way to write native compiled software for BlackBerry, it's such an impenetratable fortress with no successful viruses or malware ever written to run on it. (many companies love the BlackBerry's strong security).

I see where this is going...

The BlackBerry OS is a hardened operating system. You're not going to find any information related to how it functions. If that information was readily available, people would be attempting to hack it to pieces. You can't make changes to it. It's a closed system. It's not for you to tamper with.

If you want to develop applications for the BlackBerry, then get the SDK for it, and start programming. Beyond that, you're not going to get any help "learning" about the intricacies of the actual OS.

Yes he was.

Siva: There is little published about the BlackBerry OS. That's one reason why there are no viruses. If you are interested in hacking the OS, or in virus writing, may I suggest you look elsewhere.

Everyone trashes the poor old 7750.

I loved my 7750 . . . I still have it in fact . . . Yes, it was a turtle, but it got the job done. It had the best keyboard of any BlackBerry. It was built like a tank. It had a superb form factor. The scroll wheel fell naturally where my thumb rested, unlike the faster 7250 which had too short a frame for my hands! You could review all sorts of emails etc. without your hand cramping up.
The screen worked great in bright sunlight, but couldn't compare indoors to the new ones of course!

The perfect BlackBerry would be the 7750 box with the guts of a 8800 series inside.

A moment of silence please for the late 7750 (or 7780 . . . only slightly faster.)
