I've been running iOS5b3 for quite some time without any real problems. Yesterday I decided to install "Find my iPhone" app, tested it and everything worked fine. I went to bed and when I woke up my iPhone is suddenly useless... It asks me to "finish the final step" and configure the Location Services. I can choose to enable or disable the service, but both options end up in a message saying something like 'Iphone activation failed, your iPhone cannot be activated because the activation server is temporarily unavailable. Please connect to iTunes to activate or try again later' Could be somewhat different cause I'm translating it from Dutch and I can't find any info on this problem. (I cannot connect it to iTunes because version 5b3 has expired and when I use 5b5 it says the version is 'too old', but that's not what I'm here for!) Also my phone doesn't seem to connect to my carrier although I'm using an officially unlocked iPhone. I can still hear the new-email-sound from time to time, so my device is definately running in the background. People cannot call me though. Double clicking the home button doesn't work. The only thing I can do is RETRY. I can't get passed this nonsense... Here are some screenshots of the only things I can do/see: "It could take up to 3 minutes to activate your iPhone" "Activation failed"
