I had posted a article about improve your iphone & ipod touch  ,make it a powerful PPC on April.And now I’d like to rewrite it into  English version, and add some new feature such as something about IOS4.  Though my English is very poor, hope your guys would love this post.  Thanks.
So let’s start it now.
Chapter 0.Prepare
1)Jailbreak and Cydia

We  all know that apple had limit some useful iphone&ipod touch’s  functions, such as background task , flash, and so on. So I would like  to tell you how to make your iphone becom powerful, it can support  background tasks and become more beautiful, actually we’ll release all  it’s power now.
First of all, your iphone should be  jailbreak.This article is write for firmware 3.13, IOS4 is a bit  different from 3.13, and I’ve written another article for IOS4, if you  don’t know Chinese, please wait till I translate it.
So, now we  should jailbreak your iphone, if you don’t know how to jailbreak ,just  google it and ,it’s so easy. You can use spirit, ultrasnow or  jailbreakme to jailbreak your machine. These software are all very easy  to use.
And then we assume that your iphone is jialbreaked, you  should see a cydia icon on your springboard like what this picture shows  below.(ps: I’ve installed a software called five-icon-dock so my dock  can shows five icons, if you’re interested on it ,you can open your  cydia and search it , it’s free.)
Cydia is just like App store,  but the software on it can be only installed on the jailbreak machines.  OK, now you may need a WIFI or 3G network, make sure that your iphone is  connected to the internet, then open Cydia , manage->Edit->Add,  add several new sources to your source list like below. The source can  be simply knew as the sites that supply apps, if you don’t know any  thing about UNIX or MACOS, it doesn’t matter, just add sources and then  you can download many free software.

Here is the source list that you should add:
http://app.weiphone.com/cydia/ weiphone source,威锋网提供的源
http://apt.weiphone.com/cydia/ weiphone source again,威锋的新源
http://d.imobilecinema.com/ imobliecinema source, IMC源
http://www.sinfuliphonerepo.com sinful source, you can find out many cracked software on it, even those  paid software on Cydia. sinful 源,里面有大量破解软件,包括cydia的收费软件的破解版
After that, search ipa patch and afc2 patch on cydia and then install them. Important~!
And then install cydelete, use the same way. Cydelete  is a software that allow you to delete your software which installed  through Cydia with the same way as your normal apps. Just press your  gapp icon on the spring board for a second and then all the icons would  be shaking, then press the “X” button on the left top, the software then  be deleted.
2)install iFile, iFunBox and install0us

After  prepared your Cydia, we’ll now start to install some other software.  Now we still cannot install deb and ipa packages though we had cydia.  But most software we download through the internet are ipa format. So  we’ll use iFile+iFunBox+install0us these software to help us install  more apps. BTW, if you do know there is a software called  ”(91assistant)91助手”, please don’t use it ,it could make your iphone  crash ,crash , and crash.

So now we search cydia and install  iFile and install0us. We’ll use iFile to install deb packages, and  install0us to install ipa packages.(ps: The last version of ifile become  a paid app on cydia, so you need to chose the sinful source one if you  don’t want to pay for it,it’s cracked.). Then download iFunBox to your  computer. It’s a desktop software, just google it and get it ,it’s free.  We’ll use it to transfer files between your iphone and computer.

After  that you can transfer the ipa packages into your iphone ,in this path:  var/mobile/Downloads, and open install0us on your iphone, you’ll find  that the ipa shows on it, then click it and installed, it’s easy.
It’s  the same way to install deb packages use ifunbox and ifle. And ifle is  more powerful than installous ,it can manage all ifles on your iphone  ,so be careful , don’t delete any important files on your iphone, it may  have serious consequences.
Then is all for prepare step , we’re ready for the transformation now.
Chapter 1.System transformation 
This chapter is about some system functions, break apple’s limitation on iphone, make it powerful.
1)backgrounder+Proswitcher+Activator

make your iphone support multitask and app switch.
Iphone  or ipod touch could not run app on the background ,many people know  that. In fact ,apple is a company that lead by designers ,so they would  only publish any thing that they though fixable for users. Iphone  3GS/ipod touch 3G or older version are not powerful enough to support  multiple task, so they won’t let these functions release. And iphone 4  is support multi task now.
Tough apple limit these functions ,we  can still use it. First, download and install backgrounder, proswitcher,  activator through Cydia. Somebody may rather to use mQuickDo, but not  me. Anyone who is interested on it can try it.
Well, now let’s  change the settings of these apps. I give my settings below, if you  don’t like it ,you can set it as your way. ^_^

Open  backgrounder->control, cancel the default hotkey(home  button->shorthold), and then select “sleep button->shorthold” to  change the deault hot key. After that if you hold the sleep button for a  short while ,the screen will display this message:”background enable”,  then is running on background. If you would to cancel the background  running, hold the sleep button again , it should display ”background   disabled”.

Next we’ll set proswitcher. After installed the  proswitcher, open “settings->proswitcher->activation methods” to  set the hot key that you want to start the proswitcher. I set “home  button->short hold” as default. Here is a picture below:
2)orbit to make a spring board overview

Sometimes  we may installed too many apps and get tired for turning pages on the  spring board. So we’ll use orbit to make a fast switch between the  spring board pages.
Set the “settings->activator->home  screen->home button->double press->orbit” so orbit would be  start when you double press the home button on the screen. If you had  set double press on home button to start ipod , is OK, ipod would  display more a button to start orbit on the ipod control panel.
 
3)SBSettings

Well  it’s SBSettings now. WTF is this? Well is a software the content many  on-off to help you turn on or off some functions of your iphone. Before  the IOS4 release, iphone got no switch to turn off the screen rotation,  so when I’m reading books on my bed, is a really a tired work. Using  SBS, had installed a switch called “rotation”, anytime when you swipe  the status bar, it come out a control board and you can turn on or off  any functions that you want.
Though IOS4 can turn off rotation, SBS still get more useful functions, like autolock, wifi, buletooh, and so on.
Here are some recommend switches:
Rotation
Autolock
Keepawake
4)iMoblieCinema
Iphone and ipod touch still do not support flash, even on IOS4.
Add  the IMC source I’ve introduced at the beginning, and then enter this  source on Cydia, find imobilecinema and install it. So your iphone can  watch some online flash video now~!
A software called Frash can also play flash but not much. And is IOS4 only.
5)Chinese input method

I recommend Baidui input method. The default Chinese input method is so disappointing that I cannot say any thing.
6) iBlueNova, Good Reader, Stanza,Safari download manager

iBlueNova  can transfer files between your iphone and any bluetooth device, er, OK  , I just test it with my NOKIA mobile phone , and I don’t know if is  work between computer and iphone, but I think it should work.
About  goodreader,  goodreader can open almost document, like PPT, doc, all  kinds of pictures, pdf, and so on, it’s really a awesome app.
stanza is a ebook reader.
safari download manager can make your mobile safari download any files through the internet
 
7)aNote, iXpenselt


Awesome note is a very popular app and it’s really very useful.
iXpenselt can help you record the expend and income every day and is useful ,too.
8)volumeButtonControl

Here  is the last one. This app make your iphone’s volume buttons become the  controller of ipod. Short hold of the loud button, ipod will play the  next song, short hold both buttons ,ipod would be pause/play. Its  useful.
