Ok, this is how it goes down.
I rarely decide to write more than two words (Usually Hi or No) but on this occasion i feel compelled to let you all know how i feel about this subject as it is fairly close to my heart. Add to the fact that my backlit keyboard is wonderful and i enjoy typing in the dark.
Anyway i digress, back to the next generation iPhone;
NOBODY and by that i mean no person that will ever use ClioSport will ever know about the probable successor to the iPhone 3GS. Not one single user paid or unpaid has the knowledge that you require to answer your question.
Any rumour you hear will be entirely fabricated or based on the assumption that obvious technical advances will be pushed out to future iphones (OLED, LTE, Bigger Pixel Counts, 802.11n and RFID)
Patience is a virtue. Don't ask f**king stupid questions.
