    Herro!

    I have my iPhone 4 with 4.3.5 and I plan on getting iOS 5 but I'm afraid that it will slow down my phone significantly. At which, if it does, I'd like to downgrade. How do I ensure I can downgrade after?

    Also, is "the plan" to have iOS 5 jailbroken rather than 4.3.5 ? I wanted to jailbreak but I do not have my former SHSH blobs. :(

    Thanks in advance!

    Out if experience i can tell you iOS5 will make your iPhone 4 a lot faster. Especially web browsing improves a lot. Some benchmarks show that Safari in iOS5 is nearly twice as fast.

    I'm on 4.3.3 now. I'm unable to save the SHSH using tinyumbrella and iSHSHit. Can't i save the SHSH blobs for the firmware which apple is not signing now, even though i still have that firmware on my phone?

    Will we be able to downgrade from iOS 5 back to 4.3.3 using the normal methods of saving our shsh with tiny umbrella and using that?

    This is what I need to know. If there is no chance of me going back to my JB 4.3.3 if i dont like ios5, i don't know if I will be giving it a try.

    If anything, people are reporting the iPhone 4 to be twice as fast with iOS 5.

    This alone might make me want to lose my JB for now as my phone is currently running extremely slow.

    Best program to save cydia hacks/installs for when ios5 gets JB'd?

    I believe I have already read that the Gevey will not work with ios5. Maybe I am wrong and read that it wont work with the 4S.

    This.

    I've tried looking around, can't find a really clear consensus on what's the best way to do it or the best app.
