At first I had some reservations, to buy a non-original battery, but already in the packaging they were gone: Very professional and beautifully packaged and pre-charged. Nevertheless, I have first fully charged him.
After almost 3 months I am very happy with permantem WLAN to get even "only" 24 to make ends meet, but with a mixture of HSDPA, EDGE and WLAN and moderate use of loose times 48h together.
The battery is in fact really super, the radio characteristics of the i9000 but unfortunately modest. So I have eg. In flight mode is one 35 minutes music. The battery has not lost a percent!
Therefore recommended 100% in terms of value for money!
