MyWi is iPhone application which creates wi-fi hotspot on iPhone and enables tethering through 3G network.

I had already been aware of this app when Cydia alternate app directory "Rock" was released, but it didn't work well on my iPhone at that time.

I tried it once again, and now it works so fine. As its developer said, it seems work faster than PdaNet because of using native routing process, and it uses less battery resouce than PdaNet.
It supports also USB and Bluetooth connection.

MyWi is so nice app that it's worth jailbreaking.

I think WEP should be upgraded to WPA2.

By Dev-team's so much effort, JailBreak and SIM unlock was succeeded on iPhone software 3.0.

New SIM unlock app for 3.0 "Ultrasn0w" works fine with SIM card of NTT DoCoMo.

Most of apps which I need runs smooth, but I forgot to uncheck Pineapple logo of QuickPWN. Anyone knows how to change boot logo without restoring again? "LogoMe" can not be installed and does not run correctly in 3.0.

Boot logo image seemed to be loaded from flash ROM.

Ustream.tv is a web site where you can broadcast your video and watch videos broadcasted around the world.

They released Ustream client for iPhone. It stream videos so smooth. And you can also record the streamed video on iPhone.

This is the most tiny and easiest way of broadcasting system in the world.

Cyntact is an application which enables contact list of iPhone's AddressBook to display photo icon.

I don't register photos of my friends in AddressBook, so you can see only icons on the left side of the list in the sample image.

I guess this function will be applied officialy by Apple in future release of iPhone OS.

New version of Modem application for iPhone "PdaNet" supports USB connection (Windows only).

WiFi Router Mode and USB Mode are listed in its new settings.

This version is more stable and reliable than previous version.

We have two major tethering application for iPhone.

One is PdaNet, and another is iPhoneModem.

PdaNet uses so much resouces while tethering, but it seems to be more stable and reliable than iPhoneModem.

I prefer PdaNet though iPhoneModem is distributing the tiny app "iPhoneModem.app" which creates Ad-hoc network automatically. This app is so useful with PdaNet.

StreetView of Google Maps was supported on iPhone software 2.2.

Drawing street view is not so fast, but I can enjoy and utilize it anywhere with iPhone.

iPhone firmware 2.2 released and was broken by new released QuickPwn.

It was so easy as previous version, but I couldn't restore JB software with AptBackup (It doesn't seem to work without restore by iTunes.)

Anyway, 2.2 runs fine after the pwnage.

Sonic Vox is voice changer app for iPhone.

It changes the tone of your voice just by saying to the iPhone's microphone. Sliding horizontally your finger on the screen makes it's tone higher or lower, and vertically moving adds effects to your voice.

This is not useful app, but just for fun.

Direction (経路) of iPhone's Map has not been available in Japan for a long time.

Now it is available in some place and part of Japan.

GPS on Google map is very useful, so this support becomes one of reasons to purchase iPhone.
