I just got me an iPhone4S as business contract 'upgrade'.
Yes its quicker than my 18month old 3GS, somehow the edges feel, well, sharper in the hand than the last one, and it has more bells&whistles (same plumber/RGI friendly extra apps though).
the move upwards is not such a big leap forwards as it was from a standard Sony Ericsson to the 3G.
So, gotta get to grips with iCloud, and SIRI (voice activated commands). Facetime is great fun though - oh yeah did I mention it now has a torch built in for the camera function - wow - but,how come it has took two redesigns to get it in? - and no signal problems either.
