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!
