6680 help?

Hi all

could anyone help me with my phone please. My 6680 sometimes becomes extremely slow when typing an sms and sometimes reboots on its own at random.Also, sometimes it allows 1000 sms in inbox but of recent,says memory full at 250.I have a 512mb mmc in. Is there any way of diverting my inbox to the mmc?and what is the easiest way to add some games to my phone? Any help would be much apppreciated thanks.

In messaging, select settings in the options mebu. there select 'other options' ..There will be an option called 'Message storage Memory'. Change it from Phone memory to Card memory.
