Hey, I was recently trying out various things to get the App to download correctly on the iPhone 5.
I found that using a proxy helps.
I remembered an old solution for Slow PlayStation Network Downloads.
That seems to work for me. It definitely gives an improvement.
I used an old PC with 54G connection to act as the proxy server using Privoxy.
My internet connection speed is 4Mbps and tops at around 409KB/s.
Since my net connection is slower than the 54G router, I don't think that the PC would be a bottleneck. The router is Wifi-N though.
I was not using any other computer while trying this out.
I downloaded a 20Mb App.
With the Proxy Disabled the App took exactly 6 minutes to download.
It works to 57 KB/sec
With the Proxy Enabled the App took exactly 2 minutes.
This worked out to 173 KB/sec.
Although not the ideal 409 KB/sec the 173 KB/sec felt blistering fast to watch.
Could some else verify the same with a faster internet connection and a better local network.
