I had a couple of options to transfer my contacts to the iPhone 4.
Option 1: The simpler option suggested by everyone – copy contacts to SIM card and then copy them over to the iPhone – Done.
It was doable, but I wanted it more systematic and some contacts had important information like city, email address and even postal addresses.

I looked up online for information on how to backup data from a Moto Rokr E6, and all I found were solutions using the Motorola Phone Tools software(This software comes with the phone in a CD).

Option 2: I tried searching for the Motorola Phone Tools(MPT) software online, found one link, but it said it will take me 4 days to download 80MB of data. I gave up on that. That’s when I remembered that I had the CD that came along with my phone somewhere at home.
Reached home, knew where to look for the CD and found it in no time. Next, find a Win Computer(That installer works only with Windows).
Went to my friends place with the CD and tried installing it on Windows 7. That software was written in 2006 and I had very less hope of it even installing, but guess what, it installed without any problems and ran also.

Problem 1: My phone wont get detected.
Tried connecting it using USB, and some other tricks. None of them worked. Then it came to my mind that this piece of software(MPT) was written back in the days of XP.
Right click -> Properties ->  Changed compatibility to “XP Service Pack 2″ and ran it. Voila! It worked, my phone got detected.

Without wasting a minute, I hit the back-up/restore option in that tool. Connecting …. DONE. Backing up …. DONE.
At this point I was somewhat sure that my contacts are backed up and lying somewhere in the computer.

Problem 2: I didn’t know where the file was saved and in what format.
I had a tuff time finding this one(I haven’t used windows for 3-4 years now). Looked in Program files & every other place. Didn’t find anything related. Hidden files – yes, that option was enabled by default.
Changed those settings and I had a “Programs data” directory that appeared, digged a bit into it and found the MPT folder, it had two .mdb files, contacts.mdb and events.mdb. Microsoft Access? WTF! That’s what I said first, and since Microsoft Access was already installed on the computer I thought this would be a cake walk. But wait … the moment I opened it, it said – The software is expired and I can’t open the file.

I’ll summarize what happened here. I downloaded a free viewer from the internet and opened the file. Those files didn’t contain the data I was looking for – my contacts.

The search continues.

After looking around for a while, I fond another interesting folder – SyncML. Opened a bunch of random folders in it and there goes two text files – contacts.txt and events.txt, both files with file size > 0 KB. Phew!
This is how the contacts.txt file looked like:

BEGIN:VCARD
VERSION:2.1
N;CHARSET=UTF-8;ENCODING=QUOTED-PRINTABLE:;xxxx
TEL;VOICE;WORK;CHARSET=UTF-8;ENCODING=QUOTED-PRINTABLE:+012345678
X-MOT-CAT;CHARSET=UTF-8;ENCODING=QUOTED-PRINTABLE:Phone
UID:00001
END:VCARD
BEGIN:VCARD

Ok. Now I have some data to play around with.

Emailed this file to my mail account and came back home.
1. Opened Gmail & created a new group in the contacts section.
2. Tried the import option and selected the contacts.txt file
3. It worked! All contacts were imported.
4.  Export contacts in .vcf format.

Downloaded  that file and imported it in Address Book. Done.

Never ever throw away the CD that came with your mobile Phone
