Don't get us wrong, enabling the Ovi Store was a pretty sweet add-on in the last update -- but the second N900 push in just a single week features a list of fixes and changes that should put smiles on a few owners' faces, too (and a few devs' faces, for that matter, while they wait for this payment bug to get patched up). This time around we've got full support for Swiss keyboard layouts, better compatibility with 3-branded SIM cards, support for Microsoft Exchange Server 2003 in the handset's Mail for Exchange service, and a handful of performance and usability tweaks for Ovi Maps. It'll be available both over-the-air and via PC download in a phased global rollout over the next day, so keep checking; no need to get all crazy about it if you've already installed the first update, though -- you'll be automatically alerted when this one's ready for you.
