Thank you.

With Sprint, you have to request it by speaking to a representative at *2 or via email support. There is no way to request it via any codes in the handset.

They will then flag your account for an update, and you then call back to *2 and it will let you know the update is happening.

I'm asking about the technical information: what data my phone sends to the network, what data it receives, and how that data accesses my phone filesystem.
It's not likely people here know this stuff, but maybe somebody can at least point me in the right direction.

actually, it IS likely someone here knows that. the users here are EXTREMELY knowledgeable; some Sprint techs are helpful contributors. although i don't know the answer, i do know someone here does.

don't knock SU.

OK, I found it.

The standard for OTA activation is TIA/EIA-683-C. I have yet to find the actual document though, cause the link on the TIA site is broken.
Another document, a standard for OTASP (service provisioning) 3GPP2 C.S0016-A is freely available for download on http://www.3gpp2.org/Public_html/specs/C.S0016-A_v2.0.pdf
There's a very detailed info on all aspects of OTASP procedures. It's dated 2001, so things might have changed. If only somebody could tell me how all this got implemented in the SprintPCs network.

In case you're wondering why I need it, I'm interested in mobile phone security, and I want to know if the OTA PRL update procedure can be exploited.
Hopefully I'll find out before the bad guys launch some nasty virus.

found the latest standard - http://www.3gpp2.org/Public_html/specs/C.S0016-C_v1.0_041025.pdf dated 2004
It points at TIA/EIA-683-D, which I can't find anywhere.
I wonder what's the difference between the two.
