Here is the Data Throttling Hack for Sourcery 1.0.
I did the hack my self and applied it to mine and it booted up fine.
This is only for the main rom with no theme just plain blue. I have not tested this with a theme on so feel free to try it on a themed one but its not my fault if anything happens.
First boot up will take longer then normal.
Mobile Network Settings will Force Close.
Download: 1.1 coming soon
1. Put the .zip on your sdcard.
2. Use ROM Manager or boot into recovery and install it.
