Is there a way to circumvent the 20MB file limit on iOS without jailbreaking? I travel often enough that I decided to activate tethering through AT&amp;T. I'm not on unlimited data, but I do have a fairly high limit now (tethering comes with more bandwidth) I am often downloading new podcast episodes over 3G, but find I am still limited by the 20MB file limit. So I have to tether to my Mac Book Pro to download the podcast (over the iPhone), and then sync it to my iPhone.

I guess the reason for the 20MB limit was when AT&amp;T offered unlimited data, but now it is just annoying as it requires me to take an extra step to download the same 20MB file over the same 3G network.

Short of having another iPhone and tethering them together, is there a way I can download a file over 20MB directly to my iPhone? I'd prefer not to jailbreak it, but I guess I am not completely opposed to it if that is my only solution.
This is a limit imposed by Apple. 


  Cellular downloads are limited to a file size of 20 MB or smaller.


See comment below, iOS 5.1 has increased this limit to 50 MB.
