Yes, it's an addiction I can't kick...the bigger screen will be the excuse I use, but to be honest, my 4S is all the phone I really need...just can't prevent it whatever I do, and will be pre-ordering on Wednesday
I'm the same my contract doesn't end for 3months so have time to hang out and see if i like the taller screen. Maybe just renovate the 4 and hang out till 5S.
Same here in regards to the size of the current iPhone. Although I'm still waiting till the announcement to see if I'll upgrade or not. I just got my White 4S 2 weeks ago so it feels like I have a new iPhone now.
