I can make one if you are.
Let me know which version.
Here is the uncapped data mod for BB v0.6.1
download, and move from sd card to /system/framework and overwrite the service.jar in there. Reboot.
The reboot takes a while, but let it sit...it will boot up. Similar boot time as wiping dalvik cache.
Can make this for other versions of BB too if interested.
