    Some.

    Opera, IceBrowser, NetFront, Escape, AvantGo, Pocket IE and others.

    Unlike the desktop browser market, where people can get completely
    adequate browsers for the cost of downloading it, the PDA, mobile phone
    and embedded browser market has more potential to be profitable. The
    user exchanges money for the browser when they bye each device. So many
    browser manufactures provide browsers for use in that context and some
    specialise in the PDA/Phone/embedded browser markets (e.g. NetFront and
    Escape).

    It is also not unusual for a PDA/Phone/embedded browser to give no real
    indication in it's OS or GUI (and frequently User-Agent headers and
    navigator object information) as to which specific browser is being
    used. The browser may have been sold/licensed as a component and
    integrated into the device by its manufacturer. Fortunately modern
    browser scripting practices don't require any knowledge of the specific
    browser in use so this is not a problem.

    That varies. Assuming an implementation of ECMA 327 ("ECMAScript Compact
    Profile") should be safe. Many will actually implement a full ECMA 262
    3rd edition version. In practice (W3C) DOM support (and dynamic DOM
    support) is more significant. There is a tendency for browsers on small
    devices to be less dynamic than desktop browsers (device memory
    constraints and slower processors may necessitate that in some cases).
