I've been using an iPhone 4 for the last 2 years. It's been a great phone and I will pick up the iPhone 5 once it releases.
The only thing I wish Apple would do would be to add multitouch/multitasking gestures to the iphone like on the ipad. ( http://www.businessinsider.com/ipads-multitouch-gestures-2012-7?op=1 )
I installed Zephyr, (http://www.geek.com/articles/mobile/zephyr-jailbreak-tweak-adds-multitasking-gestures-to-iphone-20111229/ ) but still I'd rather have native support for them (like on the ipad!)
My iPhone 4 will go to my girlfriend to replace her 3rd gen ipod touch (similar specs to the iphone 3gs.) She won't use it as a phone. Her phone is a Seiko Portus. ( http://www.sii.co.jp/wx/02s/index.html ) Not really a smartphone, but it has a built-in 42Mbps wi-fi router so she can use it with all of her wifi devices (ipod touch/soon to be iphone 4, wifi ipad 3 and 3ds/psp.)
