That's easy! Sports armband, mobile and earphones! One comms kit!
On all models? and I'm pretty sure that if the other person doesn't have an iPhone (e.g samsung galaxy S what ever number)then this wouldn't work.iPhone users have an advantage! Free conference calls!
Bluetooth headsets...And what, we use sticky tape to attach large smartphones to the sides of our faces? Proper comms are a good idea, just not sure how this could progress lol. It would probably be cheaper to buy actual gear than 3 iphones... there's no point getting free conference calls when an iphone 5, for example, costs over 400 pounds to buy!
Bluetooth headsets...
Its a gadget so its a must have, right @HullRef? Whilst you are very much correct @Pierluigi it is still nice to watch them talk about sticking phones to their heads!Lads, whilst it's a nice idea the need for comms is a hell of a long way off for us all!
