State v. Saqib, ___ Iowa App. ___, 2004 WL 433967 (March 10, 2004) (trial counsel ineffective by failing to file motion in arrest of judgment to challenge guilty plea on grounds that neither written plea of guilty nor in-court colloquy informed defendant that guilty plea might affect immigration status; failure to move in arrest of judgment does not bar challenge to guilty plea if failure to file motion in arrest of judgment resulted from ineffective assistance).
