Skaink, your english is fine and thanks for the reassurance, i think i will see how it goes for a week before sending it in, today the whole day it seemed to be working fine again on "dual" but i am bit afraid to try a reboot. i shall try it tommrrow lol.
reboot or not doesn't make a difference just be patient and have it on GSM or DUAL mode to receive your calls, am sure that in a few days you 'll have 3g signal back again, i know it's annoying but you can't do much....
