[#2]

have you installed any kind of task killer recently? very strange issue, I strongly recommend to repair/reinstall your software... then would check for reception and normal use before update or backup anything else...

[#3]

do you know how to reinstall the soft for the phone and how can you flush it ?it started to work again after i've done an update but now i've lost the reception. can anything be done about it???

just follow my previous suggestions once again to see if it will work and fix the issue.
