Hacking psvita 3g sim module / homebrew

[leerz]

Hello, hope you don't get the title wrong.

I'm actually searching/asking how to talk to the gsm modem on the vita, ive browsed the vitasdks very very briefly and I've not found it.

I'm thinking of doing some sort of P.o.C for vita sending sms natively instead of doing it via Google.

Any chance you could poke at the TEL_SET_OPERATOR.ini I swear if we could change those flags on the vita 3g in the us it will allow for an unlocked sim.

"on the 3G version of PSVita, the daughterboard containing the broadband chip utilizes an extra Toshiba TY890A111222KA Mobile SDR SDRAM Memory." source http://www.edepot.com/playstation.html

Can that memory can be usable?

That would be pretty amazing

I now have leads for the 3G/Tel stuff
these are the apps

loc NPXS10043
not  loc NPXS10021

stuff related to the app

vs0:app/NPXS10043/sce_sys/icon0.png
vs0:app/NPXS10043/sce_sys/livearea/contents/bg0.png
vs0:app/NPXS10043/sce_sys/livearea/contents/default_gate.png
vs0:app/NPXS10043/sce_sys/livearea/contents/template.xml
vs0:app/NPXS10043/sce_sys/param.sfo
vs0:app/NPXS10043/sce_sys/pic0.png

unsure if the attribs can be found in

.rco    Resource Container Objects
.sfo    System File Objects

such as

vs0:app/NPXS10021/tel_reg.suprx
vs0:app/NPXS10021/tel_reg_main.rco
vs0:app/NPXS10021/tel_reg_plugin.rco

I don't know if these files are even writeable since they are in vs0
I don't even know if they can be modified (if there's a filecheck / it would definitely brick) (imagine secureinfo_a for the 3ds)

a sim unlock to pick up any mobile operator would be perfect
