[mandzhalas]

I have spend last 12 trying jailbreak my iphone 3g
To start off my iphone locked to network and i need unlock
It has 06.15 ipad baseband

It had 4.21 software at start but i couldnt jailbreak it,so it was downgraded to 3.13 using folowing metod:
connect iphone to pc
press shift and locate 3.13 wich i downloaded from website.
itunes gives me 1015 error
iphone screen has conect to itunes logo
open tiny umbrella and press exit recovery
wait for iphone to reboot
open redsnow and trie to jailbreak
REDSNOW GIVES ME THIS EROOR:"SORRY THIS NOT SUPPORTED YET ON IPHONE 3G"
i tried to manually locate 3.13,but still same.same was with 4.1 software
i cant pass this point

also i have tried greenpoison and spirit.but they will not recognize that my iphone conected


can anyone give me clue where to start.i have read allot of guides in last few hours,but cant actually make jailbreak

Upgrade/restore to stock 4.1
Error 1015 pops up
Run tiny Umbrella and use Exit recovery to kick out error
Now at Emergency Screen.
Activate it with official sim or hactivate and jailbreak it with Redsn0w 0.9.6b6 MEGAUPLOAD - The leading online storage and file delivery service
Your Cydia should work fine now, update cydia and install ultrasn0w to unlock.

that worked a treat!thanks man! all i needed is RIGHT version of redsnow

now other problem is after succesefull jailbreak i have no wifi.So,i cant use cydia for unlock.
Trying to google now see if there is any way around this

Use idskaid, ifunbox or iExplorer , download ultrasn0w deb file and drop it in Cydia/autoinstall folder > reboot, you are unlocked.
If there isn't any autoinstall folder > create one on desktop and drag it into the Cydia directory
