machine.
Nokia Symbian C++, Java, Python, Flash, Runs mostly anywhere.
WRT

Make the web a first class dev tool.
Be open, transparent and free.
Adhere to standards when possible.

Wash, Rinse, Repeat...FAIL
1. First, install all these:
o iPhone SDK
o Android SDK
o Blackberry SDK
o Windows Mobile SDK
o Nokia WRT SDK
2. Download the PhoneGap source.
3. Map to each SDK.
4. Copy your app into each.
5. Build for each.
6. Fix a bug.
7. GOTO 3.
Automation FAIL.
