Voice over Internet Protocol (VoIP) calls using applications such as Truphone and Fring are nothing new to the iPhone. VoIP calls using 3G, or EDGE/GPRS for that matter, have been available for three months now, and it's the jailbreak app VoIPover3G that makes them possible.

The app works by using a MobileSubstrate library that tricks applications into behaving as if they are on a Wi-Fi connection when they are actually on a cellular data connection. Fring and Truphone are tricked by default when VoIPover3G is installed using the Cydia package manager.

Firmware update 2.2.1 (5H11a) for iPhone and iPod Touch is now available from Apple via iTunes. Besides some bug fixes, 2.2.1 also includes a baseband update, which brings the modem firmware to version 02.30.03. The iPhone Dev-Team immediately suggested that users with jailbroken and/or unlocked devices wait for further instructions while they continue to inspect the update.

Apple has just been awarded a far-reaching patent titled "Touch screen device, method, and graphical user interface for determining commands by applying heuristics." Does this sound enough like an iPhone? The patent may be the first step in a legal battle between Apple and Palm over the Palm Pre. The two companies have already started to exchange harsh words.

Two new Apple patent filings have recently been published that could possibly be incorporated into the next generation iPhone. The first is an audio jack cleaning adaptor for portable electronic devices. Two different methods of cleaning would both essentially force compressed air through a conduit and hollow channels in the plug to displace lint and debris that have accumulated in the jack.

According to Apple, "A consumer could place the adaptor plug in the jack, couple the conduit to the plug, and then apply compressed air through the conduit to clean the jack." Although this sounds perfectly functional, the second patent may actually be more useful on a day-to-day basis.

iPhone owners using iGoogle as of late will find that the site has changed its look. In fact, the iGoogle address formerly devoted to the iPhone now redirects to a standard Google mobile website. Why did Google opt to remove what was arguably the superior interface, and replace it with a site that is more difficult to use and has less features?
