timmyj9 on iPodTouchFans has figured out how to enable street view of the iPod Touch on firmware 2.2. Apple let out this fiture for iPOd Touchs and only included it for iPhones.
EDIT: HERES A BETTER WAY TO DO IT THAT MAKES IT SO YOU DONT GET THE NO SERVICE ERROR MESSAGE. CLICK ME
Heres how to do it,
“1. get this file via ssh: /System/Library/CoreServices/SpringBoard.app/N45AP.plist
2. convert to xml at http://iappcat.com/plist/bin2xml
4. save then using that website again reconvert to binary
5. rename original file N45AP.old
6. copy new N45AP.plist in (make sure permissions are 644)
7. reboot ipod
all new Maps features work however you get a searching for service (replaces the word ipod in the top left) and waiting for activation message that pops up occassionally, music settings disappear also music slot in prefs disappears (hjrry)”
Please comment whether or not this has worked for you.
