Upgrading a Windows Mobile 2003 2nd Ed. Pocket PC to Media Player 10 Mobile

Zack Whittaker over at MSBlog.org asks how to upgrade a Windows Mobile 2003 2nd Edition Pocket PC to Media Player 10 Mobile. And, the answer is:  Not from Microsoft. Windows Mobile devices are more like applicances than computers. The large ROM-based applications like Media Player must be burned-in rather than simply installed on top of whatever is there. These firmware based applications are updated by the device manufacturer (not Microsoft). It tends differ from manufacturer to manufacturer. My Dell Axim X50v device, for example, got its Media Player 10 Mobile upgrade with the large AKU2 upgrade Dell made available last year. HP and other firms provided similar upgrades.
