Answer 1

Only image/png is supported by old browsers (WebKits) and this is the only codec you can rely to be present. img/jpeg get added later on and is still not supported by many browsers.

For Android 2.3: try if you can do it in vanilla browser. If it works there then it is a PhoneGap issue and should be reported to the authors.
