Boost recently announced if plans on throttling data down to 256k after a 2.5GB capped is reached...
Note - I used ES File explorer rather than Root Explorer
1. Root your phone
2. Perform a nandroid backup if possible
3. Download ES File Explorer from the Play store
4. Open ESFE and go to settings -> Other Settings -> Root Settings. Check all four boxes.
5.
I came across this and it seems to work. So, I thought I'd share it with everyone.
Disclaimer:
I cannot be held responsible for what YOU do to YOUR phone. With that said let's start!
(FYI: I use Root Explorer for this)
1. Preform a CWM Backup if you do not have one already
2. Make sure you are in WiFi or Airplane mode, or are not connected to 3G
3. Open root explorer and navigate to '/data/system/'
4. Find the 'throttle' folder and change the folder permissions to 'Owner:' 'Read' and 'Execute' only. (r-x------)
5. Open up the 'throttle' folder, you should have 2 files in here, one is 'temp' and the other is something like '-1226839461'. Backup these files to your SD card in case you have problems.
6. DELETE both files in the 'throttle' folder.
7. Clear Dalvik Cache
8. Reboot.

Tips - Once inside ESFE press the up button until you are at / . Then find the throttle folder. After saving a backup of this folder just in case, select it then press the menu hard button. Choose Operations and scroll down to Properties. Where is says Permissions, hit the change button. Then in the top row uncheck the write box and hit ok.
Final Step - change your 4G and 3G settings too,
