Curious thing about the "official" Twitter client we saw a few weeks ago. According to CNet, that version does not support access to the Photo Hub ergo uploading photos was not possible. That was a huge dent in the social network app, especially since many of us like to take pics and well...Tweet them.
Arne Hess, of the::Unwired fame, has been jonesing for a decent Twitter app for his Windows Phone 7 Samsung device (and we don't blame him).
Tonight was his night as Seesmic (see demo) was finally released to the Windows Phone Marketplace (it's of course, free). He immediately Tweeted from said client and sure enough, Seesmic supports photo uploads from his WP7 device (as evidenced above). Very exciting.
What does this mean? Well, it may mean the developers of the Seesmic app had native-code access and worked closely with Microsoft. Well, that's just our hunch.
Update: Arne just mentioned this as well: "Features not (yet?) supported in @ for Windows Phone 7: Notifications (new tweets, @, DMs), landscape, predictive text, in reply to"
