Hello, new to this site as you may tell. For reference, I'm on an iPhone 5 running iOS 6. After downloading an an app on Cydia, PDAnet, the download did not complete, and ended in an error. It then asked me to restart my springboard, which I did. But after restarting my springboard, the iPhone booted up, took me to an iOS 6 setup screen, and required an activation. This is obviously concerning because I already activated my iPhone awhile ago. I tried to activate it both using my cellular connection and a WIFI connection, and both methods resulted in an error message, "Your iPhone could not be activated because the activation server is temporarily unavailable." Why did I have to activate my phone again, why is not letting me, and why did this happen after trying to downloading this Cydia app? Thanks!
