Popular tech blog Product Reviews is reporting that a number of O2 users are waking up today and finding no signal bars on their phone, which they have featured the image shown above. This had been taken from an iPhone 4S, although looking at the comments below their article it seems this is a much bigger problem. There are well over 100 comments of users reporting O2′s network is down, and these include both iPhone users and those on other devices.
The O2 network problems started yesterday afternoon, UK time, and have continued through today. Within the last two hours O2 posted a status update explaining the 2G service had been restored. If you are using an iPhone on O2, are you experiencing signal problems today?
