I'm Richard, I work for Dexrex (www.dexrex.com), and we're are starting a beta of Dexrex Extensions for Symbian S60.
Dexrex allows for free, secure, and private archiving of SMS text messages on your Symbian S60 cell phone onto your account on www.dexrex.com. Dexrex also allows archiving of IMing on Windows and Mac, and SMS texts off of Blackberry.
I'm hoping to find some interested beta users here. Looking for feedback, ideas, concerns, or whatever else.
