Hello everybody,
i am from india just unlocked my iPhone3G (4.2.1) with the help of my carrier "Airtel" by tethering method like he told me to connect my phone to itunes and restore with another sim card and bingo it worked.
Now i am here coz i have read/heard a lot about jailbreaking the iphone but i am a bit scared as it is my office/business phone and i have my calender flooded with so many to do list. I have downloaded redsnow as i heard it is better then snowbreeze. Anyways i have some queries so please help me?
1. Why is shshs blob do i need it as they say u do not need it with 3g?
2. Will it delete my calendar as the update 4.0 iOS did it and i was badly stuck with my calendar.
3. Will it be faster ?
4. Can i jailbreak my iphone3g 4.2.1 with redsnow and what i need to do it?
5. Recently i have downloaded firmware ipsw 4.2.1 of 329mb as the ipsw is not available in my itunes folder even after showing hidden files etc.
5. What i need to downgrade in future?
6. Is there anything i should be worried about like taking backups?
7. What is baseband will it effect my iPhone?
8. So many questions my god plz help?
I am confused with so many sites giving the information in so many ways.
Awaiting for your replies at the earliest. Thanks in Advance.
