    When I connect my S3 the ID:COM goes pale blue instead of Yellow?
    Is this a sign that something is not quite correct.

    UK S3 user on the Three network. Just done the update yesterday and now I don’t have access to text messaging. Reset APN’s and requested new OTA setting for my MMS/Text service with no joy.

    Just re-flashed in the vain hope it would work and still no joy. Anyone any idea’s?
