To Downgrade or Not to Downgrade?
So I just recently jailbroke my phone and found the wonders of third party apps. Unfortunately a lot of those apps don't work as well on iOS4 and they're features I'd love to have seeing as I have an iPhone 3G. At the same time, I'm hating how slow iOS4 runs on my 3G. So the answer would seem to be downgrade to 3.1.3
But unfortunately I don't want to lose my game data / texts that I've had on iOS4 since its release (seeing as you can restore 3.1.3 from a 4 backup). Is there anyway around that? Is it even worth it - I'm upgrading to an iPhone 4 in October...?
Thanks for any advice!!
