There are few paid video recorder available in iPhone. I tried one of them but was not happy with the quality and it takes too much time in saving video to the disk. Recently I tried cycorder, which is available free of cost. I like this recorder as it doesn’t take time in saving video. Quality of recorded video is awesome. You can’t expect better quality than this in 2 M Pixel camera.
To install cycorder, you must have jailbroken iPhone which is running firmware 2.0 or above. Go to cydia search option and type cycorder. Now install it like you installed other packages using cydia.

If you have updated your 2G iPhone to firmware 2.0 or later then you would have noticed that there is no Edge setting present and you can’t use Edge on such iPhone. Specially in case of jail broken iPhone, you might want to use edge connection to access internet. To enable edge, follow the instruction set
1. Make sure that you are able to connect your iPhone to WinSCP. Click here to know more.
2. Go to /private/var/mobile/Library . Now click on Carrier Bundle.bundle.
3. You’ll see carrier.plist file. Copy this file to your computer.
4. You need to edit carrier.plist file. In case if you are using Mac then it’s very easy as there are many editors available which can open .plist binary files in text format. If you are using windows then you may use http://iphoneinterest.com/view-plist-files link to see the content of the file.
5. Upload the file to above link (Mac users too).
6. You’ll see that you file is converted to xml format. Now you need to copy the converted content and save this content to carrier.plist file into your computer.
7. Open saved file in text editor.
8. Add following entries just below tag as shown in image. Save the files.

<key>AllowEDGEEditing</key>
		<true/>

9. Replace carrier.plist file in your iPhone from this newly created carrier.plist file.
10. Reboot iPhone and now go to Settings-> General -> Network. You’ll see Cellular Data Network in this page.
11. Provide network detail and enjoy edge.

MPlayer for iPhone supports mpeg4, h.264, wmv, mp3, aac, wma, real media, and t-dmb formats. It is good to have more supported movie formats for iPhone so that you don’t need to convert favorite movies to MP4 format before playing them on iPhone. To do that, you need to install MPlayer. Below are the steps to install MPlayer in iPhone
1. Make sure that yours is jailbroken iPhone as MPlayer is only available for jailbroken iPhones which have 2.0 or above firmware. So if your iPhone is having lower firmware version you need to update it to 2.0 or above.
2. Open Cydia installer app.
3. Update all the pending updates in Cydia installer.
4. Search MPlayer in search section of Cydia installer.
5. Tap on install button. It’ll install MPlayer in the iPhone
6. Connect iPhone to WinSCP and go to /private/var path
7. Look for media folder and if there is no media folder in this location then create one. This is the folder which will contain all the MPlayer’s playable files.
8. Copy movie files to /private/var/media directory.
9. Open MPlayer in iPhone. It will show you the list of all files present in above folder.
10. Tap on any file you would like to play.

PDANet from June Fabrics is very popular in windows based mobiles. It allows you to turn your smart phone into Wi-Fi router for your laptop. It is now available for iPhone.

Unlike other software like iPhoneModem, NetShare that tether your iPhone through SOCKS proxy solution, PDANet is true Wi-Fi router. This works seamlessly as if you are connected to a Wi-Fi router. You can share internet to as many terminals you want. You don’t need to configure any settings in your browser or you don’t require specifying any IP address. This is simply another Wi-Fi router.
The only negative point in this app is that you need to jailbreak your iPhone.

A good news to Apple Apps developers, IBM has released a tutorial on how to use the Eclipse C Development Toolkit (CDT) to program native applications for the iPhone.
You can write iPhone Apps by using Eclipse IDE in windows operating system. The only requirement is that you need a jailbreak iPhone.

There has been few releases from Apple and Zibri seems to be busy with something else. Today, Zibri updated his status.
Status seems to be very diplomatic. There is nothing as such new in ZiPhone side. He is testing new ZiPhone and still not sure about it’s GA.
For me it seems that he is no more in iPhone Hacking business. The reason he has given are OK to me. Now iPhone is available in many countries. So no more country wise unlock needed. Jailbreak is only required to get installer so that one can install free apps and this isn’t fine with Zibri .

Guys here is a very good post for unlocking your iPhone 2G. Follow the instruction and you will have iPhone 2G jailbreaked. Click here to see the post.
