Hopefully the greater experience of this forum can help, I have an iPhone 5 currently on 6.1.2 all JB and running nice EXCEPT i have a faulty camera seems to be abit of an issue with the i5. Good news is apple will replace it now i know theres no guarentee of getting a new phone on >6.1.3 but IF i do can i restore from icloud back up during initial setup without it forcing an update to 6.1.4? Can't remember if it did when i got my i5 when new.
