Best offline maps for iOS 4.2.1 (iPod 2G)

I have a jailbroken iPod touch 2G running iOS 4.2.1. I tried City Maps to go and oMaps. First on did not work, second one did not offer much functionality. Is there any other app that I can try?

EDIT: Lower version of City Maps to Go works on iOS 4.2.1!!!

There are multiple apps you can try:

• OpenMaps
• OfflineMaps
• MapsWithMe
• CityMaps 2 Go (not sure if this is the one you've mentioned in your opening post)

And there is a big discussion about saving Google Maps for offline use. So maybe there's a solution for you too?

I would recommend:

Offline+Maps

Offline+Maps is the perfect tool to save maps and consult them offline.

or

City maps 2 Go

Interactive offline map PLUS Wikipedia travel guides for the whole world. INCLUDING unlimited map downloads. 100% offline. No data roaming or WiFi required. The most downloaded app of its kind. Ideal for trips abroad and at home.
