iPhone going straight to voicemail
Hi - I need some advice please! I have an original iPhone 2G. For the past week I've had problems with making and receiving calls but mainly in my home only. Over Christmas I was at my parents' place with no problems at all. Now that I'm home again I can now actually make calls successfully, but all calls to me are going straight to voicemail despite plenty of battery and network reception. I'm with O2 who are saying that my only solution is to replace the handset but this doesn't make sense - how come it seems to be fine everywhere else in London?! I was hoping to wait until June to upgrade and really don't want to do it before then unless it's my only option. But I'm loath to fork out on a new handset if that's not the actual source of the problem... All advice welcome! Thanks.
