I've just got back from the Isle of Wight festival, where I took my old phone with a battery that could last more than one day. Anyway, on getting home and putting my sim back in my desire, the call forwarding symbol was on, and saying 'forwarding all calls'. When I tap on the symbol it takes me to the call forwarding settings which says that 'always forward' is disabled, but 'forward when busy, unanswered and unreachable' are forwarding to my voicemail. I'm not recieving calls so it seems to me like something else must be up. Anybody able to help? Thanks in advance.
