No 100 mb limit for OS update

NokiaPowerUser reports that Windows Phone 8.1 GDR1 will support “zero-rating” of mobile downloads to Microsoft’s update servers, allowing users to download updates without affecting their data caps
The OEM documentation states:

This topic shows how Mobile Operators (MOs) can enable and test Windows Phone updates to work with zero-rating. Zero-rating allows users to download data, such as device updates, without being charged for data usage.

Enabling zero-rating:
Add the following two URLs to your network as zero-rated sites:

http://wp.download.windowsupdate.com

http://wp.ds.download.windowsupdate.com

Once those URLs are zero-rated, there are no more actions to take to get zero rating in place. It will be effective for all Windows Phone devices (both operator variant and open market devices). The first eligible update for zero rating is Windows Phone 8.1 GDR1.
Microsoft writes :
The update size limit is set to 100 MB by default. However, MOs can configure the update size limit and zero-rate the update downloads

So, these sites can be designated as zero-rated by carriers/mobile networks? Well, I hope they support this to get the updates out the door as quickly as possible.

Thanks for sharing this important news here!

I am waiting for this to happen... Hope it's available soon

Interesting.
