Thanks for the replys, although im not a BT customer, i am on the fon network ( using a fonera+ router) and i have used the fon network, both at home in the UK, and elsewhere.
I understand the advantages of the photos goign from card to web with minimum effort, but trying this in reality isnt quite so easy, as the few hotspots that i can use in the UK are so few and far between, and as im sure youve expeirienced the eye fi card does need a good to excellent signal, where as my phone will connect to wifi with a good-poor signal due to the phone having a bigger wifi antenna than the tiny eye fi card ( it still impresses me how they managed to get all that in a little orange SD card)
So the hotspot function works, but only in a few limited places and with a good signal, however the fon network only usualy offers 512kb speeds, and this can be slow for transfers, and you need to have a good signal - usualy right outside someones house.
Using the phone as an intermediate does mean that you loose the instant upload function however the benefit is a ,uch more reliable data conection, weather it be from the mobile operators data plan, or wifi.
Asfor speeds, on 3G data i get 4mbps, wifi via fon i get 0.512mbps, and at home on my domestic wifi i get 7mbps.
so with all that, is it worth having a subscription to the hotspot function, especialy as in my expeirience its severly crippled by a lack of compatable wifi hotspotss, when my android phone can log me in automaticaly into a much greater range of hotspots?
