Not sure if this belongs in the iPhone or iOS thread...But I don't have an iPhone 5, so I'm going to bank on this one.
Both me and my fiancee have an older iPhone (her a 4, me a 4s). The past few days, the internet on both of our phones (and a bunch of folks in my office) has been loading REALLY slow when not on wifi. Like, the point where pages just time-out. Any idea what's going on? Tried restarting, closing all apps and only opening the browser, checking for updates, etc.
problem is with the telecom operator and not your phones. Call them, maybe there is an issue with their antennas they are not aware of or they just have not cared about putting resources in their infrastructure while data usage has gone up.
Quite common in Stockholm during rush hour on commutes.
