Question about a 3GS..

[iRepairIndy]

Ok so I have a 3GS that's on 3.1.2 and I want to upgrade to 4.3.3

I want do a custom IPSW so I do not lose the baseband.. I know how to do all of that but i guess my question is this

How do I upgrade to 4.3.3 the easiest? Because I'm pretty sure iTunes will not let me.. correct?

Please help me out here.. lol Thanks

Do you have 4.3.3 blob?

Read this if you don't know how to save the blob if you ever have it saved in cydia [How-To] Using tiny umbrella to update/downgrade/restore

I guess I can save the blob when I get the iPhone, right? Since its on 3.1.2 now

If it doesn't already have SHSHs saved you can't just go and save it now. The only SHSHs you will be able to get a hold of at this time is currently signed fw versions such as 4.3.5 and 4.1, 4.2.1 and 4.3.3 are no longer being signed.

Or if you like reading the link I gave you, just run TU , plug iPhone in, request shsh blob from cydia .
Request shsh blob : request shsh blob from cydia is checked and click save shsh.
