I wrote a few days ago that the new Gmail Basic HTML view wasn’t working for me in Pocket Internet Explorer on my Dell Axim x50v, but I guess it just wasn’t completely rolled out. I tried it again later, and it worked just fine.

It’s actually quite usable. I haven’t tried it on my Blackberry 7100t yet, but if you have a mobile device with wireless access, give it a try, and let me know how you fare.
