iPhone 3g os4 too slow to work – downgrading

Posted: June 30, 2010 | Author: | Filed under: Uncategorized | Tags: , , , , , , , , | 3 Comments

As many other uses who have iPhone 3G and updated to OS4 noticed that their phone after some time is almost unusable or this. I have installed SBssetings which shows me free RAM and i noticed when RAM is lower 10MB phone doesn’t respond and can’t work properly.  (Some memory leak ? not sure)

So I have decided to downgrade to 3.1.3  and it is not as easy as you would thought.

I want my phone to be jailbreaken so you have 2 options:

1. find already customized firmware (search for customized restore firmware)

2. customize firmware yourself 🙂

Everything was ok, except that I got error 1600.

I have solved this issue by setting iPhone NOT in DFU mode but in RECOVERY mode.

There is another application for this issue “IREB” or this but it didn’t work for me (I think it works for 3.1.3 but not in os4).

How to sync google contacts with ical and iPhone

Posted: March 15, 2010 | Author: | Filed under: Uncategorized | Tags: , , , , , | Leave a comment

From MacOSx 10.5.3 (I guess) and up you can sync your google contacts with your iPhone.

Go to Address Book -> Preferences -> Accounts (tab) -> Synchronize with Google.

Synchronization will happened when you connect your iPhone to your mac and itunes starts backing up your iPhone. It will grab contacts and if there are some conflicts it will let you know.

BTW it works in both ways – now you can just modify your Address Book in mac and changes will occur in iPhone same as in gmail.

It is obvious that skype had to agree apple (we all know that it is AT&T) restriction to not be able to make calls over 3G network.

use iPhone as modem for your notebook – PdaNet

Posted: November 13, 2008 | Author: | Filed under: Apple & Mac, Mac | Tags: , , , , | 1 Comment

Everyone wants from time to time use their cell phones as modem to connect to the internet. You know those situations sitting in pub and there is some email comming you “have to” check it 🙂

AT&T lobbed Apple to not allow iPhone to be used as modem as it would shut their network. (This is not confirmed but it looks more then just opinion). So iPhone by default can’t be used as modem anyway it can connect to the internet.

There are situations where you have to be online with your notebook. So after short time there arrive applications like Netshare, iPhonemodem, … but they only allow to use proxy. So I was able to run only safari, but no skype, no VPN, no remote desktop, and other things. So this is no way for me.

PdaNet

this application will not only allows your web browsers to get on internet. This is not only proxy, but actually it works as router. That means all your application will work. I really mean ALL !!! I am now able to run Juno VPN, skype, jabber, SIP VoIP, firefox, RDP,…  I have to say I didn’t find any app which would not work. And because PdaNet is router all app will work. 🙂

How hard it is to set it up?

Easy with few clicks.

How to install it?

  1. First jailbreak your iPhone
  2. Install Cydia
  3. Install PdaNet

How-to and steps by steps are described on theiphoneblog.com with screen shots.

jailbreaking iPhone

Posted: November 13, 2008 | Author: | Filed under: Apple & Mac, Mac | Tags: , | Leave a comment

After 4 hours I got my iPhone I started to jailbreak 😉

What is jailbreak and why do I need it ?

Your iPhone is “locked”. Apple is thinking that giving users freedom will actually destroy them. So less options you have more you are happy. I understand this as developer have to make software idiot-proof anyway I am not human who likes to be locked. So Jailbreak is exactly what it says = break jail = open the iPhone to have more control and can do more usefull things

What can you do with Jailbreak iPhone?

  • install other 3rd party software not from Apps store
    • openssh server – yes you can ssh your iPhone or ssh your computer when you are shoping 😉
    • install software which didn’t get on Apps store
  • play arround as Administrator  – not only as user
  • install applications/games which are not signed by Apple – if you are developing application/game and you want to test it on your phone you have to jailbreak your iPhone to be able to install it
  • and other things

How to jailbreak?

To make it short here are steps what you have to do with links where it is presented step by step with screen shots

  • download firmware from Apple
  • downlad tool which will modify th firemware -QuickPwn
  • modify the firmware
  • get the iphone in recovery mode
  • connect to the computer
  • do last step from the QuickPWN program
  • YOU ARE DONE 🙂
