That's exactly where I'm at, I've always upgraded to newer models, but this game Apple is playing with the stingy incremental updates its getting old.Assuming JB comes for the 5 sometime in the near future, will probably be a long time before I upgrade to anything further. I suspect jailbreak releases will largely determine my future purchase of iPhones.
That's pretty much why I go with the iPhone - the software and OS. As a phone, it's not very good. Also, I'm tired of wifi dropping and various Bluetooth issues. That's a big reason I'm skipping the 5S this time around, if there is one.If it's an "S" this time around, Apple is going to be in bad shape this year. Samsung and HTC have some amazing handsets. If I stick with Apple it will be because of the IOS. Not the iPhone. Now if the handset is finally brought in line with other offerings then it'll be a no-brainer. I'll stick with the iPhone without hesitation.
