Well now that it is June, you are better off waiting three months to have the newest iPhone for a whole year.
It might be a bit of a wait s the iPhone 5 is not out yet, best wait for that version.
It is really up to your personal preference if you want to wait for the iPhone 6 or upgrade now. There is a lot of speculation the the iPhone 6 will be a great phone.
maybe around 5 or 6 hundred if you get it now but if you wait a little or until October it should probably get cheaper
This depends on your own needs and preferences. There is no single answer.
Yes it will, Both iPhone 6 and the iPhone 5 have the same lightning port on the bottom.
Whoa, getting a little ahead of ourselves, aren't we now? Wait till the iPhone 5 comes out before you start wondering if an iPhone 6 will ever even exist (It will, of course. Money, money, money.)
You can use the same SIM card for your iPhone 6 that you used in your iPhone 5.
Yes and also an iPhone 5
Yes and also an iPhone 5
The iPhone 5 will run iOS 6 or iOS 7.
There is no iPhone 6. The iOS can be downloaded to earlier handsets, yes.
Because you say iPhone 5S instead of iPhone 6, you seem to sound completely comfortable with an iPhone that will undergo plenty of under-the-hood changes will little change to the looks. I would say it is definitely worth waiting the month.
