Clearing RAM in task manager didnt help - was that what you meant?
THe flashing of the ROM oddly seems to have removed my root access - how did you get root access?
Firmware is : 2.3.3
Baseband is : I9000XXJVK
Kernel is: 126.96.36.199-I9000XWJVB-CL118186 root@DELL102#2
Should I be changing the Kernel?
Is that stock Gingerbread? I'm running Perka's rom wihich by default had ChainFire's kernel, which had root included. If you're using stock I suspect it doesn't have root access, I can't see why Samsung would provide that since usually it voids warranty.
So I suggest flashing ChainFire's kernel - if nothing else it'll give you root access which you'll need for some of your apps anyway. He also has some nice apps included which will save you having to reboot to recovery to do the likes of converting from RFS to Ext4 and whatnot.
As for clearing the cache. I meant for you to press the Menu button, scroll down to Applications. Select Manage Applications, then click the ALL tab. Scroll til you find one of the applications, then press the Clear Cache button.
Neets, and others helping.
This is the guide I followed:
Whose rom it is I do not know, but maybe this sheds some light on what I have done?
