Finally I have jailbraked and unlocked my iphone 3g
Thanks to redsnow jailreaking sw
Here is a guide on how to jail break based on my personal experience
For some strange reason Redsnow 0.93 and 0.95 b4 couldn’t identify my ios 3.1.3 ipsw file,while Snowbreeze sw identified it but ran into problems while restoring the custom firmware to the phone so I was stuck with 3.1.3 version and was waiting for the 4.0 update from apple
There were other tools like Pwange tool(which is for mac),Sprint ,Blackra they also didn’t work on firmware 3.1.3
When ios 4 released i downloaded the ipsw file and restored my phone to os 4
To restore iphone to ios 4 open itunes let it detect ur phone in the iphone section Hold the shift button and click on restore It will ask u to browse for the ipsw file after selecting the iphone file sit back and relax let itunes do the remaining work
Now we have to jailbreak the phone so I tried with Snowbreeze but ran into problems and it was damn slow
I tried with Redsnow 0.95 b4 it recongnized my ios 4 ipsw file.(Do not Use Redsnow 0.95 b4 Use Redsnow 0.93 stable version )
After it had finished processing the ipsw file. In the options window select verbose boot
Next it will ask to u get into Dfu mode to start the process
If u a first time user then Getting into Dfu mode can be a liitle ticky as sometimes you end in recovery mode and to get out from there u have download libusb 32 software and ihacksnow it fixes the recovery loop problem in a jiff
U should see these two pictures
This confirms your jailbreaking was a success
Next comes the unlocking part
Open cydia icon on the phone it comes as default when ur phone is jailbroken
In the packages add source www. repo666.ultrasnow .com
This is install ultrasnow which unlocks ur phone so that u can use it on different carriers (like airtel,Vodafone,etc)
For this installtion u will either need edge/gprs connecetion of have a wifi around
The installation reboots ur phone and voila ur phone is unlocked U should be able to see ur carrier signal strength
If u had jail breaked with Redsnow 0.5 b5
You will run into some problemn like I was not able to accesss internet through gprs/edge another issue was Mms was not there in messaging section
This was big problem as iphone without internet /gprs on the go is practically useless
After some research I found that I had used redsnow 0.95 b4 since it was a beta version
these features were not availbale
To fix this I had to jail break with Redsnow 0.93 version
So again I had to go through the cycle once again
After doing that do not Restore ur previous back up back to iphone if u downloade the ibooks app this will again stop gprs/ edge on ur phone
If u want to use the Ibooks apps that came out u should either jailbreak with redsnow 0.95 b4 or wait till redsnow releases a stable version of it
