As you may know at the beginning of the year Microsoft increased the app download cap on a mobile network from 20MB to 50MB and it has now been increased again. I think it might be 100MB limit now, I am trying to find a 100MB app to prove it but I have found an 83MB one so far which works YAYYYYYYYYYY. I have unlimited data so I have been waiting for ages for this limit to be increased although I want it completely lifted for unlimited data plans. If you set unlimited in data sense it should remove the cap but oh well a bigger limit is a start!
