What are the items of HTC extended ROM for ...

---

... and are some items useful for others than HTC TyTN? I have both a TyTN and SPV M3100 and find the bluetooth SIM access program of the HTC very useful, but can not find it on my SPV M3100. How can I install the SIM access utility from the HTC on my SPV M3100.

Who can help me?

These are applications and settings meant for auto install...

The items found in the HTC extended ROM are simply programs and settings meant to be installed automatically after a hard-reset. These programs, I believe, have been kept seperate from the main ROM in order to keep the Main ROM clean, small and responsive, while granting flexibility of choice to end users.

Thus, users may decide what to and what not to install.

Maybe some of the forum Gurus have a better knowledge of that.

Right about all except the for this -

"I believe, have been kept seperate from the main ROM in order to keep the Main ROM clean, small and responsive, while granting flexibility of choice to end users.

It doesn't allow you the choice of what to install, it installs it automatically as a part of the rom (called "customisation"), you can't remove these programs and apps. They are generally carrier specific settings and apps that are generally refered to as "bloatware" and are generally hidden so they can't be removed.
ALL cooked roms are generally devoid of these settings and apps but chefs can add their own special blend of apps to a ROM they cook.
I prefer the big storage ROMs as they give me more flexibility to install or remove apps as I like and as most BS ROMs are UC compliant (user customisation) I can setup up what apps are installed on the device at startup and remove at will if an app becomes a nuisance. All UC apps are installed on the device memory, like an extended ROM, not the sd card.

Cheers...
