Now to the business.
After installing the app, you can always see it in the menu whenever you’re running the built in browser (it runs in the background). To download an app, click on the download link of the desired app. When you’re shown the details of the app (the size and vendor…), press the menu button and select OTA download.
From there, the app downloads the app into your SD card. So no need to worry about having to search the internet all over again incase you lose your apps.
NOTE: this app only downloads OTA
