I would still keep my iPhone for sure. I would miss some of my Cydia add ons but I thankfully try to keep my add ons minimal and stick with the ones i use everyday. I would miss my tlert and sb settings (especially to remove all backrounding apps) and Mywi (which will probably be replaced by hotspot anyway).
To me that are things that make the phone more fun, I have lots of non JB apps i couldn't live without.
