        cell = [[[UITableViewCell alloc] initWithStyle:UITableViewCellStyleValue1 reuseIdentifier:@"Hello"] autorelease];

Cells should not be used to store your data. If the user enters something in the edit field, you need to copy the content to e.g. a member variable in your view controller. If the cell is scrolled out of view, it is either destroyed, or it MIGHT be kept for reuse. Either way, you can not rely on that edit field to exist anymore.
