If you are still suffering from the pain because Apple took away the Google Maps, here is some good news. No, Google has not out their Maps yet (although rumors are saying they are going to do so). Nokia has beaten Google by outing their Nokia HERE maps to iOS devices.
If you are familiar with Nokia Maps, you will have no problem with HERE. It is exactly Nokia Maps except the branding. One of the interesting features is collection. You can “collect” your favorite location. You should try it out.
