6233 Dismantling

Howdy there, newbie here.

Got a small problem. After the lcd cracked in my 2 week old 6233 a few weeks back I have now sourced a replacement LCD. Now the trouble is, how on earth do you pull it apart. The only screws I can find are under the battery cover, 2 torx 6 ones which don't help alot when I pull it apart. Are these the only ones and everything else just clicks in or do I need to access somewhere else on the phone to unscrew a few more screws?

I had a google for a service manual but wasn't able to find one. If any has one that would be a big help.

Any help muchly appreciated. Cheers :-D
