Is. .NET compact crippled by carrier ala J2ME ?

[Guest]

Or can I expect to be able to call BT apis, gps service in control panel, etc.

Specifically interested in WM Professional. It can be very hard ferreting
out this kind of info.

Thanks

The CF can't be "crippled" as it can be installed in the field. Obviously
device-specific stuff might not be there (i.e. GPS stuff won't be there on a
device with no GPS), and there are no .NET bluetooth interfaces in the CF
(see 32feet.net).

I don't believe this is necessarily true unless you know it to be.

It w/be trivial for hooks in .NET Compact framework to check for presence of
carrier or other certificates and only enable certain functionality
selectively, no?

I would be surprised if MS isn't courting carriers with ability for these
restrictions as J2ME is setup exactly this way. Carriers currently...although
most don't...have the ability to restrict unsigned cab files.

Carriers aren't exactly embracing advanced capabilities on their networks.

Do the restrictions I am mentioning (if they indeed exist) apply only to
2-tier smartphones or single-tier WMProf phones too?

thanks for help.

I know it to be true. What indicates otherwise?

It would be if they wanted it, but there are no such hooks.

For what benefit to Microsoft? The carrier can decide what can and cannot
run through signing and API lockdowns at the OS level. They don't control
the CF.

Depends on the carrier. And I can see their side too - we do wacky stuff as
develoeprs at times.

The OEM of any device has a lot of options on what they can do. Currently
the 2-tier phones are the only ones that carriers are really prone to
locking down (though most can be unlocked or purchased unlocked anyway).
