Gadget accessory maker VaVeliero has a brilliant way for you to manage two phone numbers from one iPhone: strap another SIM card onto the back of your iPhone, and use an app to delegate which one you want to use.

You don’t even have to turn off the iPhone to switch SIM cards, 9 to 5 Mac points out. It sounds too good to be true, especially since the case adds little bulk to your iPhone.
One convenient feature of VaVeliero’s companion app is that you can easily program your iPhone to switch SIM cards once you get off work at 6, or at any other time you like.
Google+ launched the Android app, G+, before it launched the iPhone app, yet the iPhone G+ app has quickly jumped to the top of Apple’s “Free Apps” list.
Facebook still holds the title for the most downloaded app for the App Store to date, due to its 750-million user base. It still remains to be seen if Google+ can compete with or surpass Facebook as a social media platform.
According to estimates, Google+’s user base has tripled from last week’s mere five million to 18 million by Tuesday. And considering Google+ is currently in invite-only mode, it’s an impressive feat that the iPhone app has jumped to the top so quickly.
When Google+ announced the launch of the G+ iPhone app, there was an unprecedented excitement hitting the social media waves via Twitter.
However, despite launching the Android app the same day that Google+ launched, Android users don’t seem to be taking to G+ as quickly as iPhone users. Facebook for Android is currently the second most-downloaded free app on the Android Market, following Google Maps at the number one spot. Google+ comes in at eighth place following Angry Bird, Pandora, YouTube and others.
What slightly differentiates G+ from Facebook mobile is that rather than grouping your friends together using “Friend” group names the way Facebook does, G+ uses “Circles.” These Circles allow users to have a more exclusive sharing platform — sharing just the right information with the right people.
