  20. Just updated to 2.3.6 last nught and my wifi problem (constantly disconnect/reconnect) did not go away. Thinking of upgrading to 4.0.3. It does not sound good with processes stopping.
    Anyone else experiencing this?
    Don’t need to root it yet, unless the wifi problem continues.

    Thanks,
    Rick
