Hi. I have tried to update the TomTom App (currently 1.5, update to 1.6) on my iPhone (3GS - OS 4.2.1) that has 4.2 GB of free space. The installed App itself uses 1.95 GB, yet I am getting a message saying that I do not have enough free space to update the App. I have already cleared out everything I am willing to in order to make space for the update (over 2GB worth!) and have turned the phone off and on again in case the deleted Apps / photos etc hadn't registered, but to no avail. How big is this update Any solutions? Thanks.
