enabling TLS and SSL protocols on iphone in ios 7

Hello, Just thought I would put in my two cents here, though I'm afraid it won't help your problem. I'm afraid that, IOS apps are, as a rule, what is called sand boxed. In other words, most things that the developer wants an app to have, they have to include it in their app. No other apps have access to it. The reason why I say this is that, I don't know what banking app you are trying to use, but mine works just fine. Loads of apps use TLS and SSL in IOS 7, the App Store and iTunes included, as well as other apps such as PayPal, eBay, Amazon Mobile, Audible, Bard Mobile, and the list goes on and on. As well as various web browser apps have it in them as well. So it is not a problem with IOS 7 specifically, but rather, the developer of your app needs to make whatever change they have to to make it compatible with the changes that were made in IOS 7. Sorry this doesn't help, but it's all up to the developer of your banking app to fix it.

SSL connections usually use port 443. Do you have this problem with both, WLAN and GSM/3g or only with either access method? Is there some odd proxy setting enabled for your network? Normallly outgoing traffic on 443 should be open, just like port 80 for http. Hope this helps narrowing down the problem. /Roland
