Not sure if this linked to the 2.2 updated but the last few days i havent been able to get data on my phone. I have an unlocked 2G iPhone with an official O2 paygo iPhone sim, which gives me free data for a year. Its worked for 2 odd months but this message has been coming up "Could not activate cellular data network : You are not subscribed to a cellular data service". Anyone else? Before i phone them. I checked online and my wifi bolt-on still is active and i got my monthly text saying its active into its 3rd month... The phone works so i assume its still activated etc Thanks.
