THANKS ITOMUTA!!!
But my english level (and my symbian level
) is low and I haven´t understood nothig, sorry 
Well, my .pkg file is:
Code:
&EN
#{"GetNetInfo"},(0xE927DA35),1,0,0
%{"Maria Manrique UC3M"}
:"Maria Manrique UC3M"
[0x101F7961], 0, 0, 0, {"Series60ProductID"}
"C:\Symbian\9.2\S60_3rd_FP1\Epoc32\release\winscw\udeb\GetNetInfo_0xE927DA35.exe" -"!:\sys\bin\GetNetInfo_0xE927DA35.exe"
"C:\Symbian\9.2\S60_3rd_FP1\Epoc32\data\z\resource\apps\GetNetInfo_0xE927DA35.rsc" -"!:\resource\apps\GetNetInfo_0xE927DA35.rsc"
"C:\Symbian\9.2\S60_3rd_FP1\Epoc32\data\z\private\10003a3f\apps\GetNetInfo_0xE927DA35_reg.rsc" -"!:\private\10003a3f\import\apps\GetNetInfo_0xE927DA35_reg.rsc"
;"$C:\Symbian\9.2\S60_3rd_FP1\Epoc32\data\z\resource\apps\GetNetInfo_0xE927DA35.mif" -"!:\resource\apps\GetNetInfo_0xE927DA35.mif"
"..\help\GetNetInfo_0xE927DA35.hlp" -"!:\resource\help\GetNetInfo_0xE927DA35.hlp"
"..\sis\backup_registration.xml" -"!:\private\E927DA35\backup_registration.xml"
In this code. I select "Ative build configuration" "Phone Release (GCCE)" and built pkg file, and the -sis file created doesn´t run in the real device because its size is 270kb.
I have seen that in C:\Symbian\9.2\S60_3rd_FP1\Epoc32\release\gcce\urel I have the another application, but not the new one. WHY??? The file in this folder, is of 14 kb and it is possible to install into the phone. I mean:
C:\Symbian\9.2\S60_3rd_FP1\Epoc32\release\gcce\urel\Other_app.exe (14kb)
C:\Symbian\9.2\S60_3rd_FP1\Epoc32\release\winscw\udeb\Other_app.exe (270kb)
The first one is right, but not second one. I don´t remerber how I get the .exe file whose size is 14 kb. I need do that with my new app.
Thanks in advance.
Best regards
