I also found out if you have the ap-DRIVE SAFELY on the STORM-2, with the 607 update  it caused it to lockup. I could not read emails or  SMS until I removed the DRIVE SAFELY ap.  So I would suggest tturning aps off 1 at a time until might go back to normal. A Tech rep told me once that the main cause for troubles on upgrades are aps that are no longer supported.
