Eseries / Communicators :: E63 - How To Check Internet & MMS Settings

I've only just discovered the E63 and purchased one. The phone seems pretty nifty, not that I need all those bells and whistles. I'm having a problem with the MMS, GPRS / WAP settings for Optus Prepaid. When I popped in my sim card when first turning the phone on, I was automatically sent these 'settings'. I was able to find my way onto the Ovi store and downloaded a few themes, so it must have been working. Now, it won't connect at all, less than two days later.

I've been exploring the phone, but I haven't fiddled with any of the internet settings, nor MMS. I've contacted Optus and awaiting a reply, and have been onto the Zoo website to send myself the settings, but the phone won't recognise them and the settings pop up as a text message that the phone is telling me I cannot open, and there is no option to save them.
