Welcome. Is there a app for iOS with the ability to pre-store a map of the city? What is important:
1) Tagging (hotels / restaurants etc.)
2) That the card was for most countries (especially need New Zealand)
3) GPS and accelerometer
4) Preferably satellite images
of course the standard map is good (thanks to Google), but without jailbreaking, I understand, to make Keshi not possible.
