Well, when you jailbreak your iPhone and start installing cydia main tools, you can see that your syspartition is too small !
In fact, the size is 750 mo, which is really short. After installing my tools, on 30mo stay on main partition. This partition is used by the system.
Here a simple way to free space, by moving 3 directory to the Apps partitions. You will need "BigBoss Recommanded Tools".
ssh root@YOUR_IPHONE_IP cd /System/Libraries #move audio mv Audio /var/stash && ln -s /var/stash/Audio #move fonts mv Fonts /var/stash && ln -s /var/stash/Fonts #remove useless textinput cd TextInput ls > todo vim todo #Remove all language you want to keep (you arrow, and do "dd" on the line to cut it). When you have finish, do ":x". mkdir /var/stash/TextInput for i in $(cat todo); do mv $i /var/stash/TextInput/; done ls #check if all language you want is their. rm todo #if you want to get it back, just move it from stash : #mv /var/stash/TextInput/LANGUAGEYOUWANT /System/Libraries/TextInput/ #Now it's time to reboot reboot
Now I have 200mo freespace ! which is nice !!!
Have fun, and feel free to ask me what you want to do this !
