    Please check that the app is MIDP 2.0 and CLDC 1.0, and the version number is 1.0 in the midlet jad only.

    Hi, Jaydeep

    The NOKIA 3230 is a CLDC 1.0 phone, based on "Series 60 2nd Edition, Feature Pack 1.

    Now when you develop using MIDP 2.0 & CLDC 1.1, it fails to even Install, and it will give you error "Invalid version".

    Try buiding it in SUN WKT or using Nokia SDK for 3230 as the target platform, keeping MIDP 2.0 and CLDC 1.0 only.
    Thanks,
    Ekta
