You need to be rooted and have ADB on your PC to run these commands. If it's confirmed this helps, i'll make the process easier with an 'installer'.[/i]
Enter the following commands in adb on your PC with your device attached (rooted, with USB debugging enabled):
adb shell su cp -rp /data/data /dbdata mv /data/data /data/data.bak ln -s /dbdata/data /data/data rebootI've done this on mine, and i'm yet to see a 'stall'. Let me know how you get on!
NOTE: This basically moves the application data stuff from the internal SD to the NAND, which seems to be faster. The caveat is that the size limit for dbdata is about 130MB, so if you go over that with your app data, bad things might happen. On the plus side, we're only moving data not the apps themselves, so filling up 130MB will take a while.
