My iPhone 5 seems to download apps VERY slowly with Wifi turned on. For a 17mb app, it can take 10 minutes. Doing a speedtest, I get just under 10mbps on the phone. Internet browsing is also fine, and the app store loads fast, it's just the actual downloads are super slow. I have done both a full reset, deleted the network settings, rebooted the phone and router and changed the DNS server several times, nothing seems to work. Anyone else have this issue? I haven't had an iPhone before, but was wondering if Apple release updates to fix these sorts of issues, and how often/when should I expect one? Thanks!
