SlingPlayer Mobile [$29.99 - iTunes Store] brings a few news features to everyone's favorite video transporter:
- 16x9 widescreen for SOLO, PRO, and PRO-HD users
- Remote access integration for DISH users
- Faster start time and channel changes
- Improved remote control UI
Thanks to AT&T's targeted terms of service, however, which specifically forbids SlingPlayer over 3G, you're still constrained to Wi-Fi (as is everyone on every other network outside AT&T, though Sling has apparently submitted a 3G version for App Stores outside the US -- no word on it from Apple yet, however).
If you give the update a go, let us know how it works for you.
[Thanks Robert for the tip!]
