ddtao asked:
As a foreigner in China, especially a tourist, do you need such PDA phone rental service with GPS, which can provide you with the city map , the discreption of the attractions and information about hotels and restaurants? How do you like it? Thanks very much.
From my experience, no.
They have good tourist maps.
Hopefully in your hotel they speak English so they can help you with everything you need to know ( their English is usually limited to yes,no and sure).
Taxi is also cheap.
