How do you download a new MIDlet? If I have an MIDP-enabled device such as a cell phone, how do I download a new MIDlet to it? Do I:
In either case, do I need a browser in the phone, and if so, which one?
It depends on what approach the device vendor implements. The vendor can enable you to download MIDlets wirelessly or to use a connection to a PC. You shouldn't need a browser, the vendor should provide the appropriate application management software on the device. For example, Motorola indicated that it will provide a free application loader on its iDEN developer Web site to download J2ME applications to an i85s iDEN phone.
Over time, the approach for MIDlet downloads should evolve to "wireless provisioning," a recommended way of distributing MIDP applications (also called "MIDlet Suites") to wireless devices. Wireless provisioning is defined by the MIDP expert group in the draft specification.
