"undo" available now in mobile gmail

One of the feature mostly used in gmail by me is the "undo" feature.I usually take a step and then sometimes i have the need to change something in it.That's when "undo" feature comes handy.Unfortunately this great service was not available in the mobile version of the gmail until recently.

Now when you use the Gmail mobile web app, you’ll have a small window of opportunity to undo four key actions: archive, delete, add or remove a label, or move a message/conversation.When you are taking any of these steps,gmail will show a yellow bar giving you the option of undoing it.This bar will stay with you for sometime even if you change the screen.Because my data account is depleted,i cant test it now with nokia 5800 but apparently this is working with android and i-os devices at gmail.com.
