Solio don't charge my iPhone anymore

I am not sure if you are familiar with the solar charger "Solio" (www.solio.com). A good idea if your iphone or other cellphones needs energy and you can't charge it.
With 2.0.1, there was no problem to charge it with the solio, but since 2.0.2, my iPhone can't be charged anymore with the Solio. When I connect them, the iPhone beeps and the symbol changes to "full battery" (even when its empty). this is bad, because the idea of solio is excellent especially when you are outdoor, travelling...
