Why do I get double entries when synching calendar with Google calendar?

Question

Since I have different iCloud passwords on my iPad 2 and iPhone 4s, I synch the calendars with Google calendar.  It works - to a point.  The problem I'm getting double entries in my IOS calendars.  Any suggestions?

I too was having this issue recently.  I decided to look into it and discovered that www.google.com and all of the search results accessed through using a google search engine toolbar were currupt.  I believe I solved this problem by updating my firmware of my router. 
Type in your IP address in your Address Bar (search using Yahoo what your default IP router address is if you haven't changed it since you got it.)  You'll then need to navigate to your router's website (ex: I search Cisco and Linksys and found mine).
Most logins to the router are
Name: admin
Password: password
You will then download a .bin file and go to your administrator page in your router's control panel and go to Firmware Upgrade.  Click the "find file" (or whatever it says) and click upgrade.  This worked for me.
If this doesn't solve it, reset the router to it's default settings by either using it's control panel or holding the reset button on the back of it in for several seconds.  This will reset any port forwarding you may have set up as well as your Wifi password.
Hope this helps,
