c500 signal problems

[Guest b21playa]

noticed the signal is bad on my c500

one minute its there and the next it drops, had same problem on both of minee.

currently got rom 4.2.1.4

i hear it isa GSM stack problem and soom roms are ok

was thinking of upgrading to 4.2.2.1 which is the french rom, will this help and if so can i put the french rom on easily enough

any other solutions?

EDIT : i have found how to roll back the GSM stack but it requires me to install cert.cab onto the phone but it says i cant do it and fails, due to restriction

how can i get past this so i can install the certificate and go back to the old GSM stack
