iPhone 4

Apple employees, unreleased iPhones and alcohol obviously don't mix well. Last year an iPhone 4 prototype was lost in a bar and sold to the tech blog Gizmodo for $5,000, which led to a desperate search by Apple and law-enforcement to recover the missing device. In an odd case of deja vu, CNET reported that an iPhone 5 was lost in a San Francisco bar in late July, and possibly sold on Craigslist for around $200. A lot of Apple blogs questioned the story because a spokesman for the San Francisco Police Department said Apple never filed a police report about the lost phone at the bar. But remember, San Francisco was the first place the elusive iPhone 5 was purportedly sited, and in July, West Coast Gadgets announced that Sprint employees would be testing the next-generation device in the city. Maybe a Sprint employee lost his prototype while sipping on tequila in the Mexican restaurant known as Cava 22 -- the scene of our crime!

According to CNET, the phone was traced to "a two-floor, single-family home in San Francisco's Bernal Heights neighborhood." San Francisco police searched the home, but discovered nothing. The unidentified man was offered money for the phone with no questions asked, but he maintained that he had no knowledge of its whereabouts.

If you've waited this long to buy an iPhone 4 or iPhone 3GS, it looks like patience will pay off at the end of this month. The leaked screenshot below shows internal documents indicating that third-party iPhone retailer Radio Shack is getting ready to slash prices on the iPhone starting today (July 31, 2011). To qualify for the new subsidized pricing customers must sign up for a two-year contract.

Both iPhone 4 models will drop $30 off the selling price, assuming the document sent to Engadget is authentic. This brings the price of the 16 GB iPhone 4 to $169.99 and the 32 GB model to $269.99. The 8 GB iPhone 3GS will also be reduced and is offered here for $19.99. We have already seen AT&T sell refurbished iPhone 3GS units for as low as one cent with a two-year contract.

Do you have multiple cell phones for personal and business purposes? A company called Vaveliero has figured out a way to help you cut back on your mobile devices. Vaveliero has invented an iPhone 4 case that allows you to use multiple SIM cards on one phone.

The accessory replaces the iPhone 4′s microSIM slot with an external SIM adapter giving you the option of using two accounts on one device.

It's unclear if you need an unlocked phone to use more than one carrier, and the different accounts can't be used at the same time. But it's a cool feature that could come in handy at the office by allowing you to carry one device to work, and by giving you the option to switch to your personal line at quitting time or during breaks.

After receiving 250,000 downloads on the Android Market, Thrutu decided to bring its popular multitasking app to the iPhone.

The app allows users to share photos and important information with other Thrutu users without interrupting their conversation. This is a great tool for giving people directions by letting them know where you are. With the touch of a button, you can instantly send someone your location and view each other on a live map while talking on the phone. You can even snap pictures of landmarks to make it easier for your friends to locate their destination.

VitaminWater has figured out a way to make your daily commute better by turning bus shelters into charging ports.

iPhones have made waiting for the bus a little more tolerable, and now you can charge your device at bus stations in Boston, Chicago, Los Angeles, and New York. The ad agency Crispin Porter + Bogusky invented the "Alternative Energy Source" -- an ad campaign to promote the VitaminWater Energy drink by offering USB ports for charging mobile devices at bus stations. Now there are two reasons to walk a few extra blocks to find a bus shelter, to stay out of the rain and to charge your iPhone.
