iPhone 'jailbreak or not to jailbreak? "

January 19, 2010 2 comments

That's the question that haunts many people struggling with the infamous iPhone to unlock (jailbreak) or not?
What are actually the advantages and disadvantages of this?

I will not dwell here on what is ascertained in explaining the operation of the jailbreak, but I want to list only briefly, from my point of view, the advantages and disadvantages of doing so.


  • Add Cydia (an alternative to the App Store)
  • Access via SSH to the device (use the iPhone as a hard drive in which to upload files via ssh of course)
  • SBSettings (Cydia) that sets up quick menu for frequently used functions (on / off services such as wifi, bluetooth, 3G, etc ...)
  • Ability to synchronize applications (IPA) downloaded from the Internet through iTunes (this is legal, so is everyone the choice to operate more or less legally with your device)
  • Unblocking a bluetooth for data transfer via the upcoming release of iBlueNove (ex iBluetooth) of MeDevil
  • Insert a firewall (blacklist) for the management of calls / SMS / MMS Input
  • Add useful features to native applications such as SMS Helper (displays a counter of characters entered in the process of writing an SMS)
  • Change the 'APN of your phone provider to not run into unwanted charges on your battery


  • For 3GS with new iBoot, unable to restart the iPhone without having to jailbreak again using blackra1n
  • Reduced battery performance (not high if you use wisely the additional services such as SSH, etc ...)
  • I can not think of much more ...

You would add something else to the list?

Google OTA (Over The Air): Mail, Contacts and Calendar! Hybrid solution ...

July 2, 2009 4 comments

After a little 'efforts are finally able to acquire a satisfactory solution to emulate Apple's Mobile Me service.

Tools and services required:

  • Mac OSX 10.5.3 or higher
  • iPhone 2G, 3G or 3GS with firmware 2.2 or higher
  • Accounts Gmail
  • Account Nuevasync
  • Lingon
  • Yahoo! account (for push email)
  • Calaboration

From the Gmail webmail set the option to forward a copy to a Yahoo! account (previously created) to take advantage of push notifications for Yahoo email on your iPhone!


On the iPhone then set your account to Gmail and Yahoo! to be notified of mail in real time.

Calendar and Contacts
Register on nuevasync and follow the correct instructions to configure the iPhone.


At this point you just have to say Addressbook and iCal to sync with their Google services: Gmail Contacts and Google Calendar.

For iCal can rely on the ease of use of Calaboration made ​​available by Google.


For Addressbook instead we have to rely to a little trickery. Enable AddressBook (Address Book) to your Mac to sync with the Gmail address book by its preferences:


Install Lingon and start it and enter a new agent (by clicking the + button) called such that will run the following command:

/System/Library/PrivateFrameworks/GoogleContactSync.framework/Versions/A/Resources/gconsync --sync

every 5 minutes (or to your liking, you can specify the time interval for synchronization between Google Contacts and Addressbook).


Also as you can see from the image I added the "Run if this file is modified" as a path by entering:

~/Library/Application Support/AddressBook/AddressBook-v22.abcddb (check the name of the file on your computer)

Now Mac, iPhone and Google are perfectly aligned and synchronized automatically in style OTA (Over The Air)! :-)

Google Calendar OTA: synchronize the colors!

June 25, 2009 No comments

After you set up Google Sync on the iPhone I have already taken steps to synchronize Google Calendar sync on my Macbook Pro via CalDev. That way I can finally get synced over the air (OTA) my calendars between iPhone, Mac and Google.

However, after you set it up properly, I noticed an annoying problem: the iPhone does not incorporate the same colors of the different calendars in Google Calendar.

Armed with patience, a good search engine and while I am came across an interesting article by Chris Carey .


  • iPhone 2.x or higher (tested also on 3.0)
  • Jailbreak done on the device
  • OpenSSH and Sqlite3 on the device
  • a little 'familiarity with the terminal

1) First thing to do once you enter via SSH iPhone, you just install Sqlite3 if it was still there:

apt-get install sqlite3

2) We continue with:

$ cd /var/mobile/Library/Calendar
$ sqlite3 Calendar.sqlitedb

3) and then ...

sqlite> select title, color_r, color_g, color_b from Calendar; -- List calendars and current colors

4) It should return a message like this (with the names of the different calendars):

Personal |181|0|13
Work |229|98|0
Birthdays-Alarms |15|77|140
Birthdays |229|23|23

5) At this point we just through Sqlite3 tell him to change color calendars we want:

sqlite> update Calendar set color_r= 15 , color_g= 77 , color_b= 140 where title = ' Personal '; -- Blue
sqlite> update Calendar set color_r= 47 , color_g= 141 , color_b= 0 where title = ' Work '; -- Green
sqlite> update Calendar set color_r= 181 , color_g= 0 , color_b= 13 where title = ' Birthdays-Alarms '; -- Red
sqlite> update Calendar set color_r= 181 , color_g= 0 , color_b= 13 where title = ' Birthdays '; -- Red

6) Finally, go out to sqlite3 by typing ...

sqlite> .quit
$ exit

That's it! Now I put my colors as you can see:


Finally I leave here the RGB values ​​of the standard colors of the iPhone:

Red = (181,0,13) = Red
Orange = (229,98,0) = Orange
Green = (47,141,0) = Green
Blue = (15,77,140) = Blue
Purple = (103,10,108) = Purple

Good hack at all!

PS: remember to make a backup before touching the file via SSH.
Pps: it is taken for granted knowledge of metodologies to jailbreak and use of basic Unix commands.

The iPhone is still growing ... iBluetooth!

March 12, 2009 2 comments

At first it was locked ... then came Zibri and the DevTeam about firmware 1.x
With the 2.0 again ... everything was locked and the DevTeam also acted on firmware 2.x

In the meantime, many applications were developed to enhance the jewel Apple held back by too Cupertino!

They were (I mention only a few):

  • BossPrefs with SSH on and off by EDGE and more
  • iRealSMS to manage individually SMS
  • Cycorder to record video
  • iBlacklist to filter calls and incoming SMS
  • Modem for tethering
  • SwirlyMMS to receive and send MMS

and finally ... just yesterday the iPhone is also able to receive and send files via Bluetooth to MeDevil with iBluetooth!
Applying the modest sum of € 3.99 (the cost of well-motivated by the same author) works only on iPhone with firmware 2.1 or higher and jailbreakati.

I can only leave you with images that speak more than words:

Change the voicemail number iPhone

January 13, 2009 9 comments

I was very tired of this key Voicemail whenever he prefixed by accident, I saw myself climbing the credit.

The voicemail button is nothing more than a quick link to call the voice mail of your phone number. However when I forget for any reason to lock the keypad to exit the menu or call, I always run the risk of touching the screen at that point by doing one (inutilissima in my case) call to voice mail.

Armed with SSH and patience I run this little hack to change the number that is called at the touch of that fateful button.

I state that I use Vodafone and that to do this you must have:

  • iPhone 2G or 3G jailbreakato
  • Firmware 2.2 installed (maybe the procedure is the same / similar with previous versions)
  • sFTP client (eg. Cyberduck or Transmit )
  • Editor .plist files (eg. TextWrangler )

The second premise is that this article does not explain, nor do I intend to do, how to jailbreak an iPhone or how to use a sFTP client and therefore its input parameters. There are hundreds of great guides that show how to perform these procedures on both Mac and Windows and other OS.

The steps to perform are:

  1. Enter in the iPhone via sFTP
  2. Surfing on your sFTP client to the / System / Library / Carrier Bundles / Vodafone_it.bundle
  3. Edit the file carrier.plist with TextWrangler (it's always good to make a backup copy of the original)
  4. Save everything and restart the iPhone

Simply replace lines 28 and 67 the voicemail number 42020 with the one you want (in my case I put 404 which makes me receive a text message with the remaining balance)

And finally attach the images of the operation:

Good hack at all!
