Has anyone tried this app in cydia, Mywi Ondemand? a very cool app for turning your iphone to a mobile hotspot. if u av an iphone and u want to buy an ipad, u dont need the one with 3g, just get the wifi only ipad and share ur 3g connection with the ipad

BTW u can check this link for an iphone 3gs for sale

Is it true that the new jailbreak for 4.2.1 cnt last a reeboot?

What do you mean by "can't last a reboot"? I jailbroke my iPhone 4 on 4.2.1 & I don't have any issues with a reboot.

It was just something i read somewhere, .i wanto confirm from you guyz who have jailbroken 4.2.1 b4 i do mine

Mind linking to what you read? I jailbroke mine using Greenpois0n RC5 & used Redsn0w 0.9.6rc8 to install cydia & hacktivate. I have absolutely no issues besides being on a locked baseband (03.10.01) which has nothing to do with the JB.
What your phone's firmware/baseband version & do you require an unlock?

Sorry . . . i misread

Greenpoison fixed that problem

http://news.yahoo.com/s/ac/20110205/tc_ac/7785818_greenpoison_releases_untethered_ios_421_jailbreak

its aiite now

I glanced through the news entry. It's saying that a tethered jailbreak for 4.2.1 (Redsn0w) has been avaiable before the Chronic Dev's Greenpois0n release. There's nothing to worry about, you can safely jailbreak your iPhone on 4.2.1.

I love My Nigeria Mobile www.mynigeriamobile.com

Tried restoring to 4.2.1, na so my phone denge pose for restore mode. . . To restore sef na wahala. . . Apparently, there's this bug with upgrading to 4.2.1 . . .error 1013 . . .or whatever it was,

After several attempts to restore sha, I googled and found the solution. . Some bug on itunes . . . had to run some terminal ish to get it sorted. .

Its bn jailbroken now sha, . nt without learning some ish lol. .

A 1013, hmmmm, what do you get when you ping gs.apple.com? I think you either used Tiny Umbrella which automatically diverts request from iTunes to a designated server (Saurik's). Anyways, the good thing about that error is that you're already updated, you just needed to kick it out of recovery. It just failed during the bb update.

-[n3rve]

Actually it didnt update. . .It just stops when updating and gives the error. . .
I've got tiny umbrella but i dnt knw zilch on how to use it lol. .Tried using to exit recovery but the same thing happened until i commented out that gs.apple.com in terminal. . .

By the time iTunes generates a 1013, it's far past the stage of upgrading the firmware itself. I did that when I needed to stay on an unlockable baseband. The 1013 error is more of a success story for jailbreakers/unlockers, l☺l. The thing is that now that you commented out the gs.apple divert (which u shouldn't do if u rely on an unlock), your baseband has been updated to match 4.2.1's BB which is 03.10.01. As such, you can't use that iPhone on an unsupported carrier for the time being. It also reduces resale value, FYI. Anyways, it's a good thing that you're jailbroken now.

I don need to Unlock mahn. . Tmobile has got the best 3g service and i got a contract with them . . . so no point unlocking. . .

Thanks for the info anyway. . safe

Just Upgraded my iphone 4 to 4.2.1 leaving the baseband at 2.10

nothing special in this firmware!!!

How did u get it to work? Did u av ur 4.1 shsh saved b4 upgrading? I tried preserving a locked 2.10 bb with no shsh saved but no success after all possible tries. Had to upgrade d bb to 3.10 since they are both locked .

Tumababa,
You couldn't preserve the baseband? How come? Didn't you get the expected 1013 error?

-[n3rve]

Got it but TU couldn't kick it out of recovery, also TU was still seeing it as 4.1 2.10 bit stuck in recovery. After so many tries I upgraded to 3.10, so I think it has to do with those with shsh saved

Ah, that's expected. TU can't kick you out of recovery when you upgrade using that method. You need libusb installed on your PC (must remove once done or it will generate a BSOD at every turn off) and iRecovery.exe. I use both softwares to establish a shell into the iPhone, execute this command:

setenv auto-boot true[quote][/quote]

After which, you do a reboot or fsboot & you should be back on. I used that to kick an iPhone 4 out of the stupid recovery loop after I preserved the baseband on 01.59.00; All dandy now 

-[n3rve] 

Why can't I modify my post post in this section? I mistakenly closed /code with /quote. I meant:

setenv auto-boot true

Heres what i did, i admit. i did have my shsh for 4.1 but i dont think that shd have stopped u frm preserving yur baseband

anyways, this is what i did.


I typed gs.apple.com, its went to the apple page.

then i downloaded TU and ran it. then went to same page and then i got to the cydia page

then i connected my iphone 4 to my pc, opened itunes and clicked on the UPDATE button.

its did its thing and brought out the 1031 error code. then i closed itunes and waited for

a while for the kick out of recovery button to appear, then i clicked on it and bada bin bada boom, its worked!!!

4.2.1 with baseband 2.10
