How to: Enable Flyover and Turn-by-Turn navigation on iPhone 4 and 3GS
Hey, guys. I was doing some searching on the Internet and found out how to enable flyover and turn-by-turn on unsupported devices, so I thought I'd share.
1) Jailbreak your iPhone and install Cydia. Redmond Pie has a great tutorial since redsn0w doesn't install Cydia yet so you have to do it manually.
2) Add http://apt.iguides.ru/ as a source. Please note, it says it may have some illegal materials in the source. I do not support you illegally downloading applications. I hope you are mature enough not to download illegally. However, this is the source the author chose to put his application in.
3) Search for 3DEnabler and install it.
4) Respring or reboot.
5) Load up Maps and 3D and turn-by-turn should work now. Enjoy
I can confirm flyover works and from what I have read turn-by-turn should work, but I haven't gone anywhere today so I can't confirm. Any questions or comments? Just post below and if this helped you press the recommend button (yes, there is a recommend button on thread posts, not very many people know about it.)
EDIT: Warning, it may make your iPhone unstable and get in a respring loop according to what I have read. I do not know if it is because of a conflict in apps or what. Just be warned it may make your iPhone unstable.
