R4 DS Card & NDS Homebrew!

While software unlocks have been available for the older iphone 3g and the iphone 3GS, the iPhone 4, with the latest firmware update and modem baseband has not been able to be unlocked purely by software alone.  IN fact, there is no way to actually unlock the phone without an iphone 4 unlock sim card like the Gevey Turbo Sim.  Before software only unlocks became available for the 3G and 3GS, the Gevey Sim was already available as a quick unlock method.  The great thing about the Gevey sim is that you don’t have to jailbreak your iphone 4, nor do you have to run custom firmware on the phone, which voids your warranty.  All that you have to do is simply put the unlock sim underneath your actual sim card in the tray, put your actual sim card on it, and you’re all set.  Quick step by step tutorial below.  So for those of you who have an iphone 4 that’s locked, or want an iphone 4, but can’t because your carrier doesn’t have them - this may just be the quick fix you need - without having to move to a different carrier, and without having to void your warranty.

STEP 1: Turn off your iPhone 4 and insert your SIM card and Gevey SIM together with the metal SIM tray provided.

STEP 2: Turn on your iPhone 4 and wait for the SIM welcome menu to show and the select “accept”.

STEP 3: At the beginning a “no service” message will show on your iPhone 4. DON’T do anything and wait until you see one signal bar appear on the top left corner.

STEP 4: After you see the signal bar dial “112″ and hang up within 2 seconds.

STEP 5: Turn on “Airplane Mood” and then turn off right away. Your iPhone 4 will show “SIM failure” and then “No SIM Card Installed”

STEP 6: Until the “No Sim Card Installed” message shows up turn on the “Airplane Mood” again and turn it off right away again. The “Sim failure” message will show and the signal will show up after a few seconds.

 

NOTE:

    * After all the steps above, if there is still no signal then power off your iPhone 4 and turn back on and repeat all the steps from beginning.

    * To use 3G network you need to turn on “Data Roaming”.
