Can you use the find your iphone app without iCloud?

I was looking for my iphone within my house, with its ringer off. So I decided I might as well use the "find my iphone app" which I have both installed on my computer and iphone. I google the app, and instead of getting the page to actually locate the phone, I get several webpages of how to set the whole thing up. Now, I finally click on this one page to find my iphone and it says "login to your iCloud account." I don't have an iCloud account. That being said, can I actually used the "find my iphone" app without iCloud? And is there any other way to locate this iphone?

Are gadgets cheaper in Singapore than in the Philippines?

I'll be going in Singapore for 4 days next month and i was hoping to have another iDevice in my collection. Maybe an itouch 5 or iphone 5c (most likely the itouch 5). Will it be more expensive here in the Philippines or in Singapore. I heard people say it's cheaper in Singapore bc of the tax refund thingy.

Also, where can i buy gadgets in Singapore? Please recommend a RELIABLE store or place. I also heard that some tourists get scammed when buying electronics. Is there any place that i can get gadgets with a low/reasonable price and is legit?
