I just received an email that had an excel spreadsheet attached and was able to preview it from Gmail on my G1 phone. Curious as to how this happened, I sent myself an email with a Word doc attached. I was also able to preview the Word document. Is this some kind of upgrade that was made? I'm pretty sure this didn't work a few days ago. Whatever the case, it's pretty cool. Next up...creating and modifying documents. Can't wait. G1 & Android RULEZ!
