Following Jasmin's thoughtful advice, I typed >x<<*<* on my K800i whick gave me a LOT of things which I dumbly jotted down, isn't it a way just to show them on the puter, at least to avoid copy mistakes?

e.g. this is what I got :
R1CE001prgCXC1250211_VODAFONE_W1R1CE001

EROM: R3A016
prgCXC1250461_EROM_DB2020_WILMA_FOTA_SIMLOCK_FLAFL A_SIBLEY_SEMCUSB

Version interface ITP
CXC 125 0310 R2N

Personnalisation

cxc1250490 R1CE001

If anyone can translate ...:(

well thanks to THIS forum site I already gathered I have a DB2020/CID51, Vodaphone branded (THAT I had already noticed !!! :D) and the firmware is widely obsolete (R1CE001). The CDA thing I now know, too.

But the rest is mainly Greek to me...
