Help me get around the 100 text per hour limit!

Ok, I"m having trouble doing this on my EVO.

Here's what I've done so far:
1. Rooted with UnrEVOked
2. Installed SDK,
3. Added to path,
4. turned on usb debugging
5. connected with usb, drivers did install
6. tested with adb devices, serial showed up
7. adb shell
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system
mount: Operation not permitted
8. sqlite3 /data/data/com.android.providers.settings/databases/settings.db
sqlite3: permission denied
