SIManager is a free app available via Cydia Store that copies the contacts stored on your iPhone to SIM card. If you are like me who changes the mobile phone frequently, from iPhone to Symbian, from android to Windows etc, this app is a real time saver.
iPhone can import contacts from SIM card but it doesn’t allow you to save / copy / move the contacts on your SIM card. But SIManager will help you to move the contacts from iPhone to SIM card.
SIManage can be installed from the iSpazio repo after jailbreaking your iPhone. The overall UI of this app is very simple. After launching the app, tap on “Copy iPhone to SIM” to transfer the contacts from iPhone to SIM. SIManager also provides some other options which are shown in the picture below.
Now if you want to move these contacts that are on your SIM to your iPhone, go to Settings > Mail, Contacts, Calendars > Import SIM Contacts. All the contacts that are on your SIM card will be transferred to your iPhone.
As I told you this app is availabe from Cydia, so you will have to jailbreak your iPhone first to download this app from the Cydia Store. If you have not jailbroken your iPhone/iPod/iPad, head over to this post to learn step by step jailbreaking process.
