### 1/5 — can't connect for two days

can't connect for two days

### 4/5 — Great!

*2011-08-28, version 1.07*

This app is great. Thanks for releasing it on the US Store. This works through a VPN in the US even though the official app doesn't. It would be even better if the graphics were retina quality. Hopefully in a future update.
