iPhone Video Recorder

Posted February 13th, 2009 by Umesh


Apple has been adamant and provided a video recording application. Moreover they have blocked any thirdparty developer from providing video recording application at the app store.

Several of us espacially ones with young kids deeply miss it. There are always those precious moments where we don’t have our camcorder and want to capture them. A Video Recorder inside the phone is perfect solution. Welcome to the world of Jail Broken iPhone. In all there are two video recording applications. The first is iPhone Video Recorder which is free to try but costs $19.95 to buy. The other is Cycorder from Saurik which is free to use and completely ad supported. Both of them can do 15fps. But there is significant difference in quality. iPhone video recorder uses much lossier compression and this shows up in recordings. I use Cycorder and am very happy with it. Here is an example video. Even though effects of 15fps is very visible, as you can see this is pretty good quality.

To install Cycorder, jailbreak your iPhone and launch Cydia. Search for Cycorder and install it. The tricky part is getting videos out of the iPhone. In order to transfer the videos of the iPhone, I use iPhone browser. This application allows you to browse iPhone file system and backup data. Use the browser to get the data from /var/mobile/Media/Videos.

Happy recording!

Tethering iPhone

Posted February 6th, 2009 by Umesh

You may be interested in iPhone App Reviews.


Recent rumour has it that Apple and AT&T are working  on offering iPhone tethering plan. iPhone is based on BSD which means tethering is rather trivial. It is the cozy phone vendor and operator relationship which makes it difficult. It is like iPhone lives in a jail with AT&T and Apple as gatekeepers. Welcome to the world of jailbroken iPhone where every thing is possible and free/inexpensive. And no you don’t brick your phone, you don’t loose synchronization with iTunes. Sweet.

Here are the steps involved.

Step 1: Jail Break your phone. The best way to Jail Break is to use QuickPwn. The Jail Break removes Apple’s monopoly over the applications which can be installed on the device you paid for. It also installs Cydia and Installer the two leading independent software managers on your device. Before you worry about abuse, Installer and Cydia both are based on open source well proven tools. I have never seen any instability because of Jail Break. The guys who did QuickPwn have been good with quickly supporting new version of iPhone firmware.

Step 2: Start Cydia. Search for PdaNet from inside Cydia. PdaNet turns your iPhone in to a WiFi to Cellular router. They can also connect your PC and iPhone using USB cable. Let Cydia install it. PdaNet comes in two versions: Full and Free. The free version restricts you to web only contents while free version allows you to use other applications like e-mail. At one time $29 cost per license, this is no-brainer in my opinion. And no PdaNet guys don’t pay me for saying so. Once installed you need to set Ad-Hoc network between your laptop and iPhone. PdaNet guys have good instructions on how to do this. I think their site can use some redesign.

In fact I wrote part of this post using tethered connection. Look at the Speed Test result on the tethered connection:

That is 2.3Mbps sweet. Compare that to 960Kbps I gets from iPhone browser based speed test. Is Apple artificially limiting download speed? Running iPhone 3G connection at this speed created large drain on battery. So, if you decided to tether, keep charger handy.

Flash on iPhone

Posted February 2nd, 2009 by Umesh

Unstrung is reporting that Adobe and Apple are finally working on flash version for iPhone. Hightime. As an at times grunmpy and at times proud owner of iPhone, I will love the idea of seeing flash on the iPhone. No more need to have special one off clients (e.g. youtube) for dealing with flash enabled web-content. Reading the Unstrung report, it seems this effort may significantly enhance the Apple SDK which other developers may be able to use.

Good luck to Adobe, Apple and all the iPhone hackers out there.
