When you look at the latest, greatest devices from Apple, Samsung, Motorola and the like all day, it can be easy to forget that not everyone out there is sporting a smartphone.

It's a good thing then, that Twitter's seen fit to update its mobile site to help offer a more uniform experience to users with old browsers, low bandwidth and handsets that don't quite fit under the "smart-" moniker. The new mobile site, available at mobile.twitter.com, rolls out today.
