Hey Guys & Gals, I have just jailbroken my 3GS (new boot) which has gone fine. Since installing a few apps and themes ect im now getting warned about a lack of space even though the device tells me i have 4gb free.

I discovered its something to do with the root partition size for installing apps too.
Is there something similar to Boss Tool that works on iOS 4 or another way i can resize that partition?

Thanks for reading.
