The default browser would handle caching the same as any browser, I would assume.

If you have a USB memory key, I recommend you install another browser - either Dolphin (very popular) or Opera. Download the APK installation file from the following links, respectively: http://www.slideme.org/mobileapp/dow...313a00d126.apk, http://www.opera.com/download/get.pl...0&nothanks=yes. Copy the APK file to the memory stick and insert it in your eDGe. Use the Library app, changing the drop down at the top left corner to "Storage". You should see a USB0 - go into that and find the APK. Click on it to open and install it. Once installed, try something like www.apple.com.

Let me know what happens
