Any issues with jailbreaking an iPhone 4?

I miss the customization of Android and seeing all of the customization options for jailbroken iPhones has made me look heavily at jailbreaking mine. I haven't done any jailbreaking since the original iPhone.

I want to know if jailbreaking using green poison causes the iPhone 4 to be any less reliable or run less smoothly than stock. I have the iPhone 4 on Verizon with 4.2.6.

No issues whatsoever. The iPhone 4 is so stable, even with beta jailbreaks like mine (Sn0wbreeze 2.4b1 with iOS 4.3.1)

As for you. Greenpois0n is extremely good. You will experience no problems as long as you follow the instructions.

I agree, I doubt you will have any issues.
The i4 runs pretty smooth JB.
