...using ZiPhone 2.4 it worked just fine. Now I have Bootloader 3.9_M3S2 and Modem Firmware 04.03.13_G. The APP Baseband Info says that I have Mode iPhone 1.1 although I'm actually on 1.1.3. Guess it's the same. Everything works fine so far....... ----------------------------now waiting to upgrade to 1.1.4------------------

@iClarified: Meanwhile we are at ZiPhone GUI V 2.4....................I used the method in the previous tutorial, which did not have the option to downgrade the bootloader from 4.6 to 3.9. Now 1.1.4 is on the market.........My Q.: should those who did not use the option (as not yet available) to downgrade the bootloader in order to get to Firmware 04.03.13_G????? With 1.1.4 out it seems to make more sense now to downgrade to 3.9.....................

Thx Russell :)
I did Restore in iTunes (to newest version which is atm 1.1.3)
Then did run ZiPhone 2.1: "ClickHereX4.6.bat will call Ziphone -b -j -a (Downgrades bootloader be warned, use for iphone > 1.1.2)"
But somehow iPhone screen was "Slide to emergency" aftewards. Only Bootloader downgrade was successful.
So again i run ZiPhone 2.1, now GUI, checked Activation, Jailbreak and Unlock.
In 2'30" i had fully working unlocked 1.1.3 phone :)
Sending sms to multiple users works, Google Maps located me on the map with right position, thanks to cellullar towers. So i suppose everything works fine. At last. :)

What happen for those that were the GeoHot early adopters With 4.6 BL ? What happens when we try to downgrade our bootloader?

Excellent app, I just try it on a otb 1.1.2 restored to 1.1.3 with itunes and executed the -a -j command and everything works but it remains in the emergency dial screen? I do not want to unlock it since I'm using a ATT sim card but not on an iphone plan? How can I jailbreak it and activate only? Any ideas....

re: Summerboard problem - it depends which themes you install - some work, some don't. Those that don't won't appear in the themes list and require an update from the author so that they work with 1.1.3.

What are advantages/disadvantages of each BL? Right now I'm only aware of 3.9BL is able to run 04.03.13_G BB. What else we can gain/lose by moving to 3.9BL?

Hi " G " I also had the same problem.. Same thing, i could not use installer cuz i installed to many apps and it got pushed off the screen... But, I did a Itunes restore and went to 1.1.3 (Iphone) then when it was finished restoreing, ran ZiPhone2.0 with the -v -b command ,, and it worked perfect.. springboard now scrolls to other screens... google maps locate thing works perfect.. all installed apps work perfect....... also another older iphone my firend had that hes been trying to get working for months,, after doing all the same steps it worked perfect..... if you getting stuck at the apple logo, dont forget to put the -v -b command......... .To Zebri -- Nice work, and thank you. :)

Tested Ziphone 1.0 and the so called 1.2 or 2.0 on a older Iphone but results are questionable, people should read up on it a little more, wait about 2 weeks....cheers !

If I download my iPhone BL from 4.6 to 3.9 with ZiPhone 1.1.2 will it ever be possible to upgrade it again, in case apple launch any update that works only on BL 4.6?

Hello again :) iClarified: pls explain sth to me as i deal with some problems. I unlocked 3 iPhones 1.1.2 OTB recently, week 45,46,47, so same thing. First two on last Sunday, where there was no ZiPhone, so used Your great tutorials, but time consuming. Never mind, worked great. The third iPhone i decided to unlock with ZiPhone. Was 1.0 version, but yesterday tried 2.0, same result, same problem. Unlocks indeed ok and seems fine, but! After installing some apps that do not fit on the screen, normally you can slide Springboard to "next screen", right? Then you can see rest of apps. Same on iPod Touch. So on my Touch it works ok, on iPhones unlocked via your tutorials also ok, but on third iPhone unlocked via ZiPhone, i cant slide! At first i was really unhappy, because installed many apps and Installer was moved onto other screen than first. So was no possibility to uninstall apps, and no sliding, so i could do nothing. Upgraded to 1.1.2, unlocked again and ok, apps gone. But problem still occurs. Cant slide Springboard. Confirmed by a friend of mine who also got 1.1.2 OTB and unlocked via ZiPhone. Pls, anyone, any ideas?

@keets28: Sorry, being in a supported country I was not aware of the tutorial How to Add an Unsupported Country to AppSupport

@keets28: here is a modified http://www.apfelei.com/uploads/hack/UIPhoneFormats.plist. It contains the numberformats for Germany, Austria and Hungary. It's a lot of work per country, that's why there's no "worldwide" solution I guess. Maybe you can use it to get your country uo and running.

keets28 - February 14, 2008 at 12:18am
i mean +++ here #### here ---- here why can't you just come up with an app for installer?
keets28
keets28 - February 14, 2008 at 12:15am
appsupport would be great if had more than just a couple number formats. i mean i don't know the right formats. could you tell me how? seems real confusing
iClarified
iClarified - February 14, 2008 at 12:10am
Why would you want iWorld. It is a hack that doesn't support proper Caller ID. Why not just use AppSupport ?
keets28
keets28 - February 14, 2008 at 12:00am
iworld for 1.1.3 that is. wtf with the hackintOsh.org site? been down all night. Javier yes that is the best way via itunes upgrade to 1.1.3 and then run ziphone 2.0 make sure you check -v
keets28
keets28 - February 13, 2008 at 11:57pm
what are the pros of dg to 3.9? besides google locate me. i would like to try this but is it worth the risk? also is anybody working on a better version of iworld? seems people need it.

Hi, I am a bit confused, why would I downgrade my bootloader if ziphone can unlock both? Also, I have a 1.1.2 Iphone unlocked with GEO method, can i upgrade to 1.1.3 via Itunes and then use Ziphone? Thanks!
