Find my iPhone doesn t work

After having my first iPhone stolen, I decided to try the app "Find my iphone" on my friend's loaner iPhone 3GS to see how and if it really works.

When I turned it on, I ensured that these were all setup:

- Location Services: ON

- Find My iPhone: ON

- Cellular Data: ON (3 Bars Service at the time)

- WiFi: ON and connected to the router

- Internet utilizing apps: ON and in use

Doing all this, I went to iCloud.com and decided to locate the phone, and test out the Find my iPhone feature.  After 5 attempts to locate and 1 attempt to send the phone a message, it still came up as "No Location" and then "Offline".

I was browsing the internet on iPhone's Safari App, while these "finding attempts" were going on.  What a miserable fail.

Now I'm wondering if whoever stole my iPhone 4S is actually browsing the internet and having a wonderful time while I sit here miserable, thinking that this feature actually provided a service that I could use to find my phone.  Appears to me, through my experience, that this is a total fluke. 

My sister's Droid actually has a phone finding app that works.  It was very disappointing to hear that her non-Apple product topped the abilities of my iPhone 4S.  As much as it hurts, I actually decided that I will switch to that new Samsung sIII in the following week.  I feel like I got jipped by my favorite company
