I’ve been thinking about iOS4 and iPhone 4 and I have 2 questions that I thought I’d pose to everyone.
Upgrade to iPhone 4?
Aparently I can upgrade to iPhone 4 with o2 in the UK from my current 3G. But looking at their tariffs they are awful. Data seems to have been restricted in a big way. So is it worth upgrading to iPhone 4?
Question 2 is more for the developers but I’m interested in all views
Will existing apps written for iPhone OS3 play nicely in iOS4? Are developers looking to upgrade apps to iOS4 to take advantage of the new features of the OS, and if you are going to do that will your apps still work ok with OS3?
