Much to my surprise, after I managed to unlock and jailbreak my iPhone using the ziPhone utility, none of the contacts I had on my card were accessible. Zip, nada, nothing.
I started to look around and noticed that ziPhone had installed the “Installer.app” utility. Taking a peek inside, I saw that this wonderful app lets one install a lot of native iPhone apps from various sources.

iSIM

The app I used was iSIM for iPhone, a shareware that imports the contacts. The free version only lets you import contacts one by one. In order to import them all, you need to buy the full version. Even with one by one(I was bored), it took me less than 5 minutes to import all of the contacts. Some extra fun 10 minutes later, everyone was in place, names were corrected, duplicates removed, contact photos were added and my contact list was in place.

Had I known better, I would have certainly used the better, free alternatives to iSIM:

SIMport

SIMport is a free app that, according to some, is better in more ways. I haven’t tested it but you could try it(on your own risk, obviously). This is the defacto contact import app, recommended by the major iPhone – related blogs. SIMport imports ALL the contacts(or only the selected ones) in a couple of seconds.
