Upgrading from 3G to 3GS

Personally, I'd say it's worth it. But then again, you could buy the iPhone 4..

Maybe this will help.

 

I bet when Apple releases iOS5 for the 3GS, it will become rather slow like your 3G. I would personally just downgrade the 3G to 3.1.3 (which should be easy since you don't need those SHSH blobs if you haven't saved them), unlike the 3GS which would need those SHSH blobs to run anything lower than what you got it with. The 3GS is good, but its already getting slow with the 4.3 update.

 

Yep.

 

For you I'd suggest holding out 'till the iPhone 5 and then using your upgrade abilities to (hopefully) get the iPhone 4 for $100.

I obviously don't know anything yet, but I suspect the i4 will run iOS 5 just fine.

 

Hey buddy, i too have an iPhone 3G and so i feel your issues about the lag.
I had mine since the iPhone 3G first came out in '08, so it's been a while and i'm just waiting for the iPhone 5 now. I suggest you do the same, you won't be disappointed, and i don't think the iPhone 5 will start to lag anytime soon with it's dual core processors!

 

its very simple PM me and i'll give you instructions

 

Wait for iPhone 5. You have waited this long
