I have a few questions, regarding IOS 5.11 on my iPhone 4S. Firstly, I find that I can only receive email whe I am connected to my home WIFI network. Is there some setting where I can change this? It appears that, when connected to other WIFI networks, I cannot get email either and I certainly cannot get it when not in a WIFI hotspot. Secondly, regarding DropVox, the app which allows you to record audio and the result of the recording is automatically uploaded to a Dropbox folder, I read somewhere that, if you are not connected to WIFI, the recording can be stored on the phone and then automatically uploaded to Dropbox when WIFI is available. I tried a short recording, when not connected to WIFI and, when recording was stopped, the app told me it was uploading the audio straight away. I can think of a lot of good reasons to use DropVox, however, I do not want to be incurring data charges from my mobile provider, each time I use it. Many Thanks for your help with the above.
