hi pinkfloyd,
for zurich i would recommend you 2 shops:
either mobilezone or digitec
mobile zone (here i bought my samsung galaxy 2):
go to zurich main station and take the tram number 3 or 14 to station called stauffacher (about 3 stations). when you're at stauffacher it's very near. oh i just saw they have many shops with google maps:

digitec:
for someone who is not from zurich it can be difficult to find. i would recommend to buy it from their online shop. but if you insist of going there you would have to go to train station "hardbruecke" or bus station "hardbruecke". from there check this map, you have to walk west from hardbruecke:
