Saving Calendar/Messages/Contacts Into Storage Car

[Guest ppc_rani]

I've recently lost my O2 XDA IIs and had to downgrade to an O2 XDA II Mini, which as most of you know has only 64MB (57.41MB, really) of phone memory.

I've bought myself a 4GB SD card to make up for the decrease in phone memory but it's useless unless I can figure out a way to backup or save my Calendar/Messages/Contacts, etc into the storage card as opposed to the default phone memory.

Is anyone aware of how to do this? Thanks.

P.S. I'm sorry if these are questions that have been asked before. I'm pretty technology-illiterate. Also, does anyone know of a software that will allow me to save ringtones/themes on my storage card? And to use mp3s as ringtones?
