Hoping I can get some sensible advice here.
I am with O2 for my iPhone 4 and have an O2 USB dongle/modem which I use to connect my laptop to the internet when out and about. I'm trying to find the most cost effective way of connecting my iPad 2 to the internet when away from home.
I was talking to O2 today about connectivity for my iPad 2 (which has WiFi and 3g but as yet no card), and they told me that there is an accessory which allows me to connect my USB dongle/modem to my iPad 2. This would mean that I don't need an additional data plan, and can use the one I have for the laptop (which is under-used). I couldn't find this accessory/cable on the Apple site, so called them. They tell me they haven't heard of it.
My question is - is there a third party cable that would do this? If so where can I get it from?
We spoke about tethering, but this means I can't use my phone whilst tethered which may be a problem for me.
Other than this - what is the cheapest way of connecting the ipad for occasional use away from home?
