Atleast with Verizon, when you battery pull the phone. The service books
that are pushed out by the provider are repushed out. My girlfriend's sprint
blackberry comes with some "Quick Launch" icons and a small program from
Sprint. Every time she has to battery pull they are redownloaded.

I already read that looking in google. Seems to be a configuration for some
services. 

I run my blackberry with a foreign country service book, since i bought my
blackberry on a foreign country, and the limitation is very low (mms, tcp
connections, and others). But, i'am connected to bis without issues.

I don't know if the service book are automatically updated when i turn on my
blackberry.

In the past i tried to mitm my blackberry connection through some software
for ssl mitm, and my surprise was that the data encrypted with SSL is also
encrypted with another algorithm into.

But, how a "mechanism for connections" could be transformed in "software
installer"?


Regards.
Aaron.

This isn't true. Through "Service Books" a provider can basically push
anything software they want to the device.

The answer:
deciding not to install the update.

I don't think it is that simple if the service provider is pushing
down software and controls the update process.  For the user to decide
not to install the update, the user must be presented with a choice.
If the install is done silently over the network in the background,
then there is no choice for the user.

cheers, i don't really had a time to take a look in deep on this
specific
case.

I'm talking the "generic". Usually, the blackberry handheld device does
not came with an automatic update software owned by your "telephony
provider" or rim. Therefore and moreover, any update should be done by
hand.

Moreover, real software updates provided by RIM should be installed
using
the desktop manager application. Usually this is not an automatic
process
and sometimes requires your handheld password to be done.

I understand that you can download blackberry updates from rim websites
according to your provider, but the trust rely in RIM who publish this
software.

Cheers,
