After performing a hard reset to try and fix a minor problem, i've suddenly lost the ability to create a mail account, sign into ovi store or social. when i go into mail and create new, it simply says unable 'unable to connect to mail server, try again later' and the error message 'network unavailable; try later' appears when i try to sign into the ovi store. he web browser is working fine. i'v tried restoring factory settings and tried restoring from a back up when everything was working fine, but now no matter i try i cannot create a mail account, or download any apps. any suggestions anybody?
ps. i've installed all the necessary software updates.
