My iphone will not load absolutely anything when it is on 3G. Has anyone had this problem on theirs before? It takes forever to load and sometimes won't at all. Thanks
And if the above suggestion doesn't help... try Settings>> General>> Reset>> Rest Network Settings -- you'll need to re-enter passwords for previously used wifi hotspots next time you connect...
I think it is normal for the iPhone 5 to take a while to download something while using a 3G connection depending on what the signal is like. Heck, mine is slow too when I am using an HSPA+ connection with a lower signal.
