Two questions about jailbreaking.
So I have an iPhone 3GS and I understand I'm able to jailbreak it and all that, but I had two other questions about the result of jailbreaking.
1. I read somewhere you lose push notifications once you jailbreak, is this true and if so, is there any kind of fix for it?
And 2. Once I jailbreak, will restoring remove any and every trace of the hack? I'm not so much worried of having to take it to Apple and them finding out I've jailbroken it as I am somehow reducing the quality of my phone. So basically what I'm asking is, once I've jailbroken is there something of that hack that will forever remain with my phone, or will a restore remove any traces of it and with it any kind of effect it could have on my phone's performance?
