With the releases of iPad Apple shown up a new OS to developers. iPhone OS 3.2 only support iPad as they said.

• Initial support for the newly released iPad
• Initial support for landscape springboards
• Includes new frameworks for recognising custom gestures, custom keyboards etc.
• Allows display output to an externally connected display for compatible 3rd party apps
• Allows user to change home screen background
• At this point, only applicable to the iPad and not the iPhone

Apple released their new tablet named iPad. As rumured it has a large (9.7 inch) multi touch screen, 1Ghz apple custom processor.

Actually there is nothing new because we see all these technologies in our iPhones. iPad has the same UI (as you see above) as iPhone. I think that apple made a big mistake by releasing iPad. They should work more on the UI, hardware, etc. There is no camera, no USB host, no more storage, … just 10 hours battery. Shame on you Steve!

Dev-Team released the new version of redsn0w that support iPhone OS 3.1.x.

You can download it here:

• Windows
  
• Mac

How is it different from PwnageTool?
redsn0w doesn’t require a system restore like PwnageTool does (it doesn’t even use iTunes at all). On the other hand, PwnageTool can prevent your baseband from being upgraded when you upgrade your firmware, preserving your unlock. (redsn0w doesn’t touch your baseband but it doesn’t help preserve it during an upgrade either). redsn0w works by modifying your current filesystem, so your existing baseband, data and applications should remain intact.

How is it different from blackra1n?
- It uses our original Pwnage bootrom exploit for iPhone 2G, iPhone 3G, and iPod 1G. (Because it’s a bootrom exploit, it can’t be fixed by Apple without a new hardware release.) Note that redsn0w 0.9 does use the USB exploit for iPhone 3GS and iPod 2G running 3.1.2, but that exploit will be fixed in Apple’s next FW release.
- It offers custom logos and verbose boot
- It installs Cydia without needing a separate download
- It’s not as fast (but redsn0w handles more variations)

It seems that Apple wants to release the new version of iPhone OS. iPhone OS 4.0 will be avabilbe only for 3G & 3GS versions of iPhone. It’s very bad news for who already have their original iPhone 2G like me!

In this guide I want to help you to choose the right firmware for your device with the speed in mind. I already test all firmware from 1.1.4 to 3.2.1 (the latest firmware as I write this article) on my iPhone 2G.

The speed factors are as below:

1. Switching between pages.
2. Keyboard speed (while typing text messages)
3. Application execution times (I know that is mainly depends on the CPU speed)

1.x

There is nothing to say about 1.x family because there is no AppStore on this family, So JUST FORGET IT!

2.x

If you remember the early versions of 2.x family (2.0, 2.0.1, 2.0.2, 2.1) is full of bugs so everyone decide to upgrade to newer version as soon as Apple release them. But by the releases of 2.2 the game changes. It’s stable, fast and accurate in action and also if you jailbreak it, it will bring all the good things that you need to enjoy your iPhone such as AppStore, Copy/Paste (clippy), Video recording (Cycorder), Bluetooth file transfer (iBluetooth), Background application (Backgrounder), etc.

3.x

The main feature of OS 3 is the “Push notification”. Actually there is no more notable things in this version (you can find full list here), all the things that they add to this version was previously resolved by jailbreakers. Beside that if you have to unlock your 2G using any kind of PWNing tools you will lose the Push ability, after that you will found a way called “push fix” by Dev-Team that bring push to your 2G but when you enable it, first of all your device will works very slowly and also you will get lots of false push alerts. The speed impact of the 3.x family on 2G was very ridicules, I think Apple intentionally do this in order to force 2G users to buy an iPhone 3GS. It may also happens because of jailbreaking.

Conclusion

If you want to have a fast iPhone 2G I suggest you to use OS 2.2 (if you already upgrade to 3.x you can easily downgrade it, i will post something about that in near future).

If you upgrade to 3.1.2 :

• Overall speed reduction
• Battery life Get
• Some Cydia application did not work properly in all situations such as iBluetooth

If don’t upgrade to 3.1.2 (stay on 2.2)

• There is no Push Notification
• You can’t arrange app icons using iTunes
• You can’t play multiplayer games (the games that runs on more than 2 iPhone)
• SMS delivery report (actually I did not test it on 2.x)

NEXUS ONE is a new mobile phone from Google!

Nothing to say…

Hmm …

Let’s think about write something about web development in  this blog …

I know that the main content of this blog is about iPhone

…

I found a new application for iPhone in Cydia called SIManager. You can manage your SIM contact in your iPhone. In this version (1.4 beta) you can also export your contacts to SIM card.

In order to install SIManager you must add the following repo in cydia then select SIManager package and install it.
